Tons of nice touches. I like the balloon animation on launch. The D pad menu designs reminded me of something - then I remembered playing R.O.R. in PlayJam7 :) I got to level 6. Found it quite difficult. If the fan made sound, I wonder if that would help me perceive how fast it is going, and how best to control it... hmmm.

Wow this is really cool! Really difficult. I only made it to Stage 7 before I took a break. There is a lot of detail here and it's clear this has been a passion project.  The first stage took me a really long time to beat. because I just didn't understand what to do.  I don't think I ever got a great feeling for how much upwards force I was giving based on my cranking. The little bar that fills on the fan moves quite quickly making it pretty hard to balance. The different color/ weight balloons were a cool twist and had me yell out "ooh that's cheeky!" haha Awesome work. I'm glad  you came back to this to start finishing it up.
