Thanks for the tip.
I checked it out again, cool game now that I know how to play :) Nice, clean UI and sound effects.
I focused on gravity upgrades and managed to get to over 2000m with two wind upgrades. The game speeds up after a few upgrades.
One problem I encountered: If you cut rope and then do wind somewhere above so that your character does not move at all, the game gets stuck and you have to restart manually. This does not happen if you do wind without cutting (then you get "retry" screen with "you got 0 souls").
