The game seems to have trouble with extremely fast clicks. I have a program spamming 100 or so clicks a second and it seems to queue a bunch of those even when I stop it (the clicks still go on for a pretty long while).
Also sorry for cheating :P
Polish suggestion: Can you make the cursor color change into the color of the balloon that you're supposed to pop? The indicator word is somewhat faint and can get blocked by bigger balloons at times.
The game is good. With a bit more polish such as more convenient control scheme (double tap direction for dash might be nice, instead of reaching down), a crash fix (mine crashed upon dying at some point. Might be something with pushing T for menu during gameplay since that's what seemed to happen), and some other spots that I forget, it can become much better. Enjoyed the concept, found the challenges fun. Good work.
