A little simple but I'd guess you're earlier on in your journey and by yourself no less. It's quite fun, the movement is pretty dialed in for gravity and friction, I wasn't annoyed by the controls at all, though I'd prefer to use mouse and wasd than arrow keys, if you're on game maker ord("ABC") is your friend .
I like the shooting and the sounds were pretty decent for what they were used for. The pixel art is charming, simple but solid. I like the boss designs, of course they spin but I like the layering of the last boss and the fade outs between phases is pretty nice. The attacks of using the wheel to teleport are thematic and raise the skill ceiling a lot which is nice.
The game isn't punishing at all, I got hit a bunch of times (because I suck lol) and I only went down to like 40% which is probably okay for a jam.
Well composed but a little barebones. It was fun!
