The core mechanic is nice, but it really gets dragged down by the floaty movement that makes the game feel really slow.
The soundtrack was nice, but there was no good end-start transition so you really notice when it loops.
The only time control related mechanic is the starting of the level after you rearranged all of the objects, which is not only minimal, but also pointless as you can rearrange the blocks even after pressing play.
That one level where you have to built a staircase out of 2 blocks is especially exhausting because you constantly have to pause to rearrange, which takes any kind of flow away, which is especially bad since this doesn't offer much of a challenge,
Overall id say its alright and could be really good with a little bit more work, keep it up.
