I'm going to be honest, I didn't expect to enjoy this one so much. But that I did, and thus I've come to sing praises (and give a little bit of constructive criticism).
First of all, for those that came because you like Konosuba, rest assured that the story is very well kept in the essence of the show, even in the crossover sections, and the characters are very well written to keep in line with their original demeanor at all times. This game feels like a Konosuba/isekai-crossover fangame and a lot of passion and effort has been put into making sure of it.
Second, for the gamers. Octopath Traveler fighting system. I don't think I need to say more, but I will do it anyway. The fighting feels SO GOOD every time. It is challenging, but rewarding, and each new enemy and boss is a fresh experience of trying to figure out their pattern and weaknesses. Switching party members feel meaningful, allocating skill points correctly for the encounters is satisfying, managing resources like mana and items make strategizing all the more rewarding, and the pathfinding that allows you to choose carefully your encounters is just cherry on the top. The fact that different party combinations get different dialogues as well in some quests is very interesting, and I only wish those would replay when I revisit the zone later with different members, if only to see what else everyone has to say.
Third, for the degenerates. Admittedly the animations are not the best they could be, but they're decent and the writing makes up for the most of it. The characters still feel like themselves and the scenes are well placed to not interfere with the story. So far there are only one-on-ones and some characters have very few or none H-interactions, but I believe this will be improved in time. I also wonder if we'll ever get some group scenes for the main party, if only as succu-dream sequences, but at least for now you're able to keep a romance going with every character simultaneously if you so wish.
Now, for the developers. This is just my personal opinion, but I think there are some things that deserve a little rebalancing. First of all, the dialogue choices that change your personality stats; there are some that appear a lot and some that hardly appear at all. In fact, in the bandit quest I was asked to have 5 of an attribute that I didn't find enough of in the rest of the game (I was at 4 even which made it more aggravating). I'm not sure if this was intentional to force the player to choose the fighting route, or if it's taking into account future updates since it's only a secondary quest, but regardless I think the game could improve on this matter, giving more options to customize our personality, even if it doesn't make a difference in terms of gameplay or dialogues. It's just such a cool and unique mechanic (I believe it's called Paragon System?) to let it go to waste like that.
Another thing that could use a little improvement is the drop rate of construction materials. Just for farming I spent like 60+ in-game days doing nothing except visiting the alleyways both morning and night, and I think in total I got... 1 material. That's a lot of clicking and resource spending (yes, days until prison are also a resource to manage) for so little reward. And it wouldn't be so aggravating if you didn't need so many materials in order to upgrade the Guild Hall enough to max out number and quality of adventurers available, just so MAYBE one of them will have stealth in order to progress main story quests... So I was thinking, with all the time we spend working on the construction (for the gold and HP increase, because it doesn't give extra days until prison, like it said it should), wouldn't it be cool if maybe 1-in-a-5 times we get construction materials item out of it? It would make sense to find those in that workplace, and it would make for a reason to even work there once you've maxed out your HP gain.
I think those are the only glaring issues that kinda rained on my parade while playing. The gold gain is pretty low and prices are very high, making it a bit grindy, but it made sense considering the setting of the story and MC. And it also provided an excuse to go out adventuring and enjoying the marvelous combat system, so it's okay.
One last note, keep in mind I'm playing on Android and the last free version (0.1.8c), so in the Patron or future versions this might have been all fixed/improved. Which would mean that the game is even better than what I'm writing right now. But even if it isn't, it's still very much worth the time to play.
