Definitely on theme for the jam.
I'm always a sucker for music and sound effects that set the mood of the game and the little funky groove had me running it a few times haha.
On the balloons that are running opposite directions, is there a programmed timing when they all line up or is it randomized? I had a couple levels where I ended having to wait for a while to get them to actually line up. That's my only real criticism.
Clean game!
