Congrats on releasing your first game! That's huge! I hope you keep making more, and as a long-time jammer I hope you keep exposing yourself to the disgusting stress of that as well hahaha.
Trying to keep a balloon in the air is a classic kids game, my game design teacher said "if it's fun in real life, it's probably fun in a video game", and this is a testament to that. I think it could be even more fun if you had to move around a bit more. Maybe you could encourage that by increasing the fall speed of the balloon? Then you'd probably have to lower the stun you get from the disruptors so you can still have time to catch it.
Again, big congrats on releasing your first game! Keep at it, it's always fun seeing people improve and change.
