What I liked about this game: I love this top-down perspective, it really works for a game like this. The art is really nice. Animation is fluid and it reminds me of classic fantasy dungeon crawlers. I also like the music and SFX, you really know how to set the mood. It got me really excited to play, seeing that knight with his awesome armor doing idle animations on the title screen!
What needs improvement: ...er, pretty much everything else, I'm afraid. There seems to have been almost no effort put into polish. The controls are floaty, almost like there are light ice physics going on. The character's direction almost never matches with where I'm going. I find it very difficult to hit skeletons, the hitbox seems really small and off-set. There are no tertiary sound or visual effects to confirm most actions, giving no satisfaction at best and confusing me at worst. And this is minor compared to everything else, but I really don't like your font choice for the dialog boxes. It's too messy and hard to read.
Please don't let any of this get you down. You've clearly got the seed of something great, here. And these problems are all fixable! I really hope to see you improve this game after the jam's over, and even if you don't, I hope you keep making games and improving at the general craft. You're clearly talented in key areas, you just need to fix some stuff!
