Nice job on submitting! Here's some feedback:
- The player needs to be able to control the camera, so much of the level was left unseen because I couldn't control the camera. Not being able to see where you are going is a sure fire way to get players frustrated. I'm guessing this was left out due to time constraint.
- The dice seem to fly through the enemies, which often makes me believe I didn't actually hit them. Having some kind of feedback for the players actions is also very important.
My suggestion is that next jam, spend less time on the level - make a short polished experience instead of a long unpolished one. Polished games always perform better in jams, length of the game doesn't add much to it.
Hope this helps! :D
