Cool game! I really like the mechanic of standing on the cube while it grows to launch yourself, it's very creative. I do think it could use a bit of extra polish- the buttons glitch out when two things are standing on them and one leaves, and I ran into an issue on the level with the long box where the box I was supposed to push on top of the long box kept getting stuck on the edge of the long box, blocking me from progressing. Still, the game has some really good puzzles and creative ideas, so I had a good time overall. Good work!
