There, Nyan! This is BOT the developer.
Since the game's release, we've had a lot of player feedback, and we've hurried to fix a few critical bugs (such as missing balloons after save).
We also included cheat codes! Try the following cheat code if you're stuck (press ~ to summon the console).
(Abusing cheat codes will make the game less enjoyable nyan!)
