I have to stress that this is really impressive! The graphics are great, the atmosphere is great, there's a shocking amount of little details strewn throughout that are really neat. And it is a goddammned shame I didn't see much more beyond the starting area because the game is also BRUTAL.
As others have mentioned the damage when walking into walls is a bit of an obstacle. I know it was in a lot of the classics, I remember discovering it when I accidentally killed myself the first time I tried Dungeon Master. But I honestly think it should be a toggleable setting for the more hardcore players rather than the default. And personally I found it was especially annoying combined with the fact the movement is very quick and sensitive. I would press a move key for what felt like less than half a second and it would move me multiple tiles.
I also experienced getting trapped by the snails, who I think were clipping through the wall behind Binro's second position in the starting area.
I like the little surprise enemy when you kill a crab, but it became annoying when I unintentionally killed a crab by simply walking forward while I had a weapon in hand.
And I don't think I ever got a handle on the combat, because sometimes it felt like enemies attacked and moved in turns. But other times it was like I'd be killed instantly by a snail even at over half health and attacking it with two clubs. Actually that's another bug, I was able to turn in Binro's initial quest multiple times, once I got 3 clubs.
There's clearly a lot of love and attention to detail poured into this game. I mean it looks and sounds great, it captures the lovecraftian feel almost perfectly, and I think it does the PS1 look better than my game!
But after about 20 minutes and a dozen deaths I just had to call it quits. If the game is refined post-jam though I'd love to try it again!
