Due to time limitations you were unable to finish the game, and that's perfectly fine! I'll try and comment on the things you DO have only!
PROS:
- Very smooth controls, very responsive
- Theme was implemented well in the form of a roguelike/lite?(I keep mixing these 2 up haha)
- You could feel the impact of the upgrades upon pickup
- Randomly generated I believe?
- Good start to something bigger for sure!
- Massive amounts of bullets yet no frame problems on my end at all!
Point(s) of improvement:
- I sometimes lost track of my character underneath all of the bullets.
- Sometimes, upon accessing different screens, my character would end up off-screen somehow.
Grats on the submission! Good luck on your future jams! :D
