I really liked how you made 3d effect with 2d assets, I've seen it done in doomlike shooter games, but I don't think I've seen any bullet hell game like that. My only issue with that was that sometimes it was hard to see exact moment when the rock was at your level in 3d space, same thing with coins. Oh, but online high scores.. that's just on another level for a jam game. Overall gamplay was pretty neat, easy to understand and responsive and explanation on a title screen was short and on point and the usage of graphics, especially particle effects, was great.
