I like the idea of being able to move the platforms as if they are a character.
the controls were a bit weird to me, might be just what I used to.
I think the thing about it is that they favor horizontal movement instead of vertical, so if I press RIGHT and UP I subconsciously expect it to jump mario style - e.g move up with a horizontal lean in the curve looks like this parabola -> 
but instead it moves horizontally "first" so it looks like this cut-section of the inverse of the parabola
also on level 3 I accidently raised the platform too high and it didn't come down xD
very interesting game though!

Wow, what a beautiful feedback xD
You are right, other person commented a similar thing. I didn't notice this while making the constrols, I will try to fix for the post jam version.
And about the platform moving out of the screen, I tried to fix that, but was too late and other bugs appeared, then I went back. I should try to fix that now.
