Floaty Balloon is a single-button game as my entry for the Itch.io Cassette 50 2020/2021 competition (see below). 

The game is restricted to memory $0000-$0fff only as per the competition.

See how far you can get in your trusty Commodore balloon by using the fire button (Port 2) to turn on your balloon burner to get higher while gravity is always pulling you down.

You can download the .prg file to run in any C64 emulator or on real hardware for the best lame experience! haha
