When I entered the first room I got pounded with thousands of bullets, and the game completely froze :( Looks fun from the screenshots, though!
Played it! Pretty neat concept -- I like how you have to time your direction to shoot the enemies, and I like how the enemies have health bars on them. The aesthetic is nice too!
A few suggestions:
- The difficulty curve is a little too steep
- Maybe let the player recover some health when they get the shop
- Rename the Build folder to bitdungeong before zipping -- just a nice little thing when people are downloading several games during a jam.
