Hey Heartbeast, fun little demo! There are a lot of things about the prototype that I enjoyed. I thought you hit a really good balance of difficulty with the slime, that was definitely my favorite enemy type. (There was a bug where the game soft locked me in a room because a slime jumped outside of the walls) Most everything in the game was readable and easy to understand. I quickly figured out the dungeon map, the combat, how to play, etc. Of course the quality of the pixel art and small amounts of polish were all a great cherry on top as well.
One of the few things I felt the prototype could improve on is how it feels to move and evade attacks. The squishiness of the combat felt great, but moving around not so much. That's not to say the movement is bad by any means, I just found it to feel too simple. Might be cool to have a dash or teleport and the directional movement feeling a bit smoother?
Anyways, very fun game thanks for sharing. I'm a sucker for dungeon crawlers with classic enemies like bats, slimes, and dragons. Excited to see how this progresses!
