Just curious, did you open the door and try the cube in it? The level becomes a lot easier once you do that. The scroll wheel was a last minute addition. Thanks for the feedback!
Yes, i did!! I spent like 15 minutes on the red level trying to take the cubes to the top, but i always fell so i closed the game in frustration :/
(I never managed to reach the top in my previous run. I'll try again now :3)
