Very long comment incoming. I just finished the Demo! I so a post on Tumblr linking this game and and the Countdown for it (I really like that Countdown thing you did by the way!), and came here to check it out. I wanted to play the Demo before the full game came out, just to get a feel for things, and because sometimes there is some different stuff (like dialogue) in the demo not in the full game, because it is demo-only stuff kind of. So I decided to play the Demo before the full game releases in just 4 days.
I am going to talk about the actual demo now! I really like all the sprites and how everyone looks, and the little animations for like when characters blink and for when Flowey attacks you. Everything just looks so good and I love the coloring. Sans and Tori's looks/designs are probably my favorite so far, defin. for the demo.
I really like all the accessibility options and captions and the all the different settings you can choose from too. I esp. like how you can take screenshots just with the S button, makes things much easier. The Self-voicing is also really interesting, it is cool that the VN is basically voice acted with it, if you so choose to have it enabled.
Some things I noticed about the self-voicing though, is that I would love if you could maybe toggle the menu thing that appears on top that says it is enabled, to make it go away or at least smaller. It isn't a really big thing, since it is already pretty small, and probably wouldn't be much noticeable at all if played full screen. I played it windowed, because I was doing other stuff, and I forgot how to fullscreen it. Would you press F?
Besides that, another thing I noticed while using self-voicing, is that it will say the numbers and letters that appear on top of the screen when you can take a screenshot. And that it also say all the stuff in the menu while you are using, both things can get a bit annoying. I don't really know if you can fix that, however, an easy thing I did was just to disable the self-voicing while taking a screenshot and when using the menu most of the time. I would maybe just leaving a post or update or something suggesting people do this as well. This is just a suggestion from me too of course. Okay, done talking about that.
I am going to talk about other menu stuff now. I really like how it looks, and I like the music menu section a lot. It is cool you can see the songs and listen to them from there. When you enter your name, it really feels and looks so much like Undertale, it is very well-done.
Now to talk about some more actual game stuff. There may some more spoiler-like/spoiler-y stuff ahead, so if people haven't played the Demo, I wouldn't really read past this point.
The in-game menu is also very good and I like the stats thing as well. I like how it looks, and I also like how the save files look. I hope in the full release though, there is more save files, maybe 2 or 3 at least would be nice, but for a demo, even one like yours, with some cool different options and choices, 1 is fine.
I really like how the "fights" are in this. Well, they are more like conversations, like Sans said, and making choices, but they are very fun, and you do them very well. It is a fun system, and I like the amount of choices for them. Which so far, the most interesting and fun choices have been some encounters with Flowey and Sans. Though being able to call Tori Mom or not, was one that I really liked too.
Like, when you originally meet Flowey, you can decide to accept his LOVE or not. Which I didn't, because I didn't want his LOVE, because I want to date Sans, and also, because he said it as LOVE and not Love, so I wasn't accepting that Flowey, I know what you actually wanted to do. Which was proven seconds later when he tried to kill me.
Then the conversation with Sans later on, which didn't go too well for me. I should have made another joke or tired flirting more, instead of trying to talk so much, and making things awkward to the point Sans took pity on me. Though, I don't think I did TOO bad, but Sans also said our conversation could have gone better, and because I accidently overwrite my load from before the date, I decided I would finish the demo and try to see if I could do better. Though even if I hadn't done that, I probably would have stuck with that and not change that conversation till the Demo was done anyway.
Anyway, I got the end of the Demo, and got a call from Pap, which is really cool by the way. And after that, I decided to reset the game to see if I can get a better conversation with Sans, I didn't realize until I had moved past the dialogue super quickly and reset a couple times thinking I had gone too far, because Sans seemed to show up earlier than the last time, that things had changed. Again, very cool by the way.
A lot of stuff changed after the reset, both Flowey and Sans really knew what was up, and I had very different conversations and/encounters with them. Even Tori knew something was a bit off, though stuff with her wasn't as different as it was with Flowey and Sans. Some different things were Flowey not attacking me in the beginning, and Sans saying we seemed bored in the beginning as well. Flowey also brought up talk about a skip button, and that became enabled. I didn't use it, but I do wonder how/if the characters would have reacted to being skipped (Sans defin. messed with you for doing that during Genocide).
The most interesting thing, was the Flowey gave me a knife right before the Sans conversation this time, which Sans noticed and asked me to please put it down. There being options to either do that ("put it down"), put it away, or FIGHT were such different options. Of course I put it away, because I didn't want to hurt Sans; I wanted to talk to him and date him. You then were given the option to either make a joke, hug, or kiss him. Which is also cool.
Something I thought about after this encounter, if Sans could be backstabbed, or like you could at least try to backstab him (not necessarily succeed at doing it) like you could in Undertale. Maybe if you put the knife away and then hugged him, that might have been an option? Because putting away might mean you still have the knife on your person, unlike when you put it down, and hugging him would probably be the best time to do it. It probably wouldn't have worked though, because Sans was already pretty on-guard with seeing you have the knife and he had just met you and so thought it was too early for hugs, but it is an interesting thought. I would try it, but that would be such a bad way to start off trying to get to know and date him, esp. since there is different stuff you get after resets, plus I don't want to hurt Sans or anyone! I want to talk and get along with everyone, and date Sans of course! Which I think I got closer to doing so.
It was also cool at the end of the demo this time around, instead of from Pap, it was from Sans, another cool change. I like the calls by way! I hope the calls stuff is in the full game, because this has been end of the demo stuff, so Idk. So yeah, I hope there is Calls stuff in the full game!
That is the stuff I got/learned so far. I haven't tried all the dialogue options and choices, and I haven't tried to reset another time, to see if there are any more changes, because I think I left stuff off well with Sans, and I would feel bad if I kept loading and resetting on him. It is really nice that there are this many choices and replayability in just the demo, and makes me even more excited for full VN in four days. I can tell you have put a lot of effort into this and I am looking forward to it!
Seeing your development log, and seeing the Act 1,2, and 3, as well as the Secret Route and Epilogue makes me even more curious to play the full thing very soon! Okay, done with my incredibly long comment/review, hope you didn't mind it.
Now to wait for the Full VN to come out; know when it does I am going to play it. Thank you for releasing the trailer and Demon of this already and thank you for making this VN! The full VN is gonna be awesome once it comes out. :)
