Your game has lots of ideas and content for such a short time, congrats! I liked the controls/cube movements and felt like the level design worked well with the "switching between cubes with different abilities" mechanism. I also really liked the little writings on the wall (laughed at one that said "Lava this way." with an arrow or something like that).
A bit hard to know where to go after the first two levels though, especially with the camera so zoomed in (it was even hard to get through a couple of simple platform jumps because of it at times…). But anyway, overall I had fun shepherding all my little cubes to safety, so good job!
