I wasn't part of the jam, but I tuned into your stream a few times and decided to play your game. Here's some suggestions I have (if you plan to work on this game at all after the jam):
1. Since dying respawns you one level back, it would make sense that progressing to the next level should heal your lost health.
2. I think the game would feel a lot nicer if the camera zoomed to fit the player and all of the enemies. Especially considering enemy bullets never change direction, so you don't have to worry about them coming from off screen unless the enemy has died since they were shot. (which could be fixed by maybe having the bullets do a little explode animation and dissapear whenever the enemy that shot them dies)
3. This one is very important in my opinion. The game should really have a hit-confirm sound if the dice you hit the enemy with was the right color. Because right now, it sounds the same as a failed hit, and I found myself often thinking I had used the wrong dice only to realize it worked
Don't take any of these suggestions negatively. I loved the game, and I understand how difficult it is to make a game jam game. These are just some ideas if you choose to continue work on the game.
