Version 4 is done! This was one of my most anticipated updates, as it adds the first really usable character ability, which lets you drop your balloons so you can quickly fall on top of another character, a risky but powerful move. The two new characters are from the gameboy game Balloon Kid, and there are two new stages from the game as well (one with a significant amount of tiles ported from the game).
