I was stuck waaaaaaaay too long in the first level, because I didn't figure out you could scale the cubes. there was just this little bit of height missing to make the jump, so I tried angling the cubes and all sorts. but it was a bit frustrating to keep getting hung up when jumping against ledges, and not being able to jump when standing on an incline.
In the end i got till the level with the cube behind two lasers in the middle path. there just wasn't enough time for me to make it :(
All in all impressive level design for only 48h, but a screen at the beginning to explain the controls would have helped me a lot.
PS: and the cubes kept tipping through the walls for me and getting lost.

I like the games art style and the sound effects. The gameplay idea is fun. The controls felt a bit funky, and I gave up already in the second level. But I liked the idea, and with a bit of polish this can become really fun to play.
