Hey there!
This game has a great look to it and the controls feel great.
I'm also participating in the game jam and can honestly say your game looks much better than mine.
If you have the chance to revisit any mechanics in the game, I would make sure that the player is bound to 1 of 3 positions. On the first level, you can just fly to the bottom of the screen and avoid everything. On the second level, you can do the same but on the top of the screen. And the third level for me, made it impossible to dodge balloons because I was in one of FOUR position on the screen, all of which overlapped with a balloon's path.
Well done, hope to see more of your stuff in the future.
