Really cool overall. Nice combat system, challenging but fair. Great atmosphere, helped by the good soundtrack. We don't see that much of it in the demo, but the setting and story seem like they could be interesting, too. Looking forward to the final game.
Some notes from my playthrough:
-"Interact" and "heal" on the same button is insane. You can't heal near interactable objects, you heal by accident when trying to interact with stuff, it's a mess. Please change.
-Using a PS4 controller, the only item I could use was the gun? With the gun selected, pull R2, character shoots, no problem. With the grenade or stamina thing selected, pull R2, nothing happens. Bizarre. Hitting the item key on the keyboard worked fine, though.
-A map would be nice.
-There should be an explanation about what each stat does when upgrading.
-If you fall into a bottomless pit, there doesn't seem to be a way to get your souls biomass back..? Seems a bit harsh. Like, in Dark Souls, you can still get your blood stain near the pit when that happens.
-Some parts seems a bit obtuse. First time I met the Red Mother, with the first armor equipped, I failed the questions. Then she didn't really want to talk anymore, so I let her be and went elsewhere. Got the captain armor, started talking to people, kinda ran out of places to go, assumed the Red Mother was important but she wasn't saying anything new... Tried attacking as a last resort, but that didn't do anything since I was wearing the captain armor, though I didn't realize that was the reason. I was confused for a while, even reset the world, but since I was still wearing that armor, Red Mother wouldn't even ask me the questions. Finally, I watched the video from the other commenter and figured out how it worked, hah. So... well, I'm not sure how likely it is that a player does the same thing I did and gets confused about how to progress, but it doesn't seem like such a far-fetched scenario. Maybe you should be able to attack her regardless of what you're wearing so that you can at least progress? Or maybe the dialogue when you're dressed as a captain should be significantly different so that you get a hint that she's not interested in talking to you like that... I don't know, it's possible that I'm just dumb. :)
-So after that I went to the storage area, got two new armor sets, got some kind of partial blueprint (?), beat a boss and got the dual beamsaber. Hmm... OK. I expected to find something to blow up floors, like the guy in the underground seemed to suggest, but there wasn't anything like that, unless I missed something. Talking to that guy again didn't do anything, even with the new recruit costume. So I was kinda stuck there, but maybe I need to talk to other people wearing the recruit costume, or find someone who wants that blueprint, or try messing with the enemy (pallid?) costume.
-It was time for dinner at that point, though, so I went "save/exit" and quit the game. When I started it up again later, the "continue" option on the title screen was disabled. It looks like it didn't save at all. Normal for the demo, or...?
