Ice Cream Air Balloon
A downloadable game for Windows
Fly a hot air balloon through the windy mountains. Collect snow from the peaks to make ice cream, then drop it in the villages. Don't hit the mountains because the balloon will deflate making rude sounds.
I made Ice Cream Air Balloon in two days as an experiment to see what it's like to use CC0 art only. I got all the art from opengameart.org, and all the sound from freesound.org.
