Very fun game, with intricate level design, it was a little tough getting the hand of controls as I mainly play with WASD, but it was still fun! I managed to get the the second last level.. I am proud of myself.
I do really like the colour pallet you used throughout your levels, and the level design is smart and well put. SFX were a nice touch as well as the particle blocks appearing randomly. I would add an option where the player can select which controls they want to use, as in movement: arrows or WASD, and it makes scaling the opposite. But that is still a great game!
