Fun entry! :) The platforming seems a little unnecessarily difficult to manage and distracts from the puzzle. If you made the platforming a lot more responsive and the jumping a bit higher, it would have been fine and kept a fluid movement, but I often found myself not being able to jump while moving left and right.
Other than that, the puzzles were smart! It reminds me of the mobile game 2048 but with platforming a bit :)
Also, some music would add an extra level of depth to the game, even some peaceful glitchy music as I could imagine getting lost in some addictive game play and nice music :)
