The controls were a bit frustrating, I would sooo have liked to be able to move using the arrow keys and not just A and D. There were some weird moments where I would also sink into the floor even though the block wasn't dissolved, or I'd bounce off a surface that wasn't a corner. Speaking of which, the bounce was pretty ingenious and also frustrating because it meant I had to be careful with my jumps lest I get bounced into an enemy, eraser ray, or some other dangerous obstacle.
I thoroughly enjoyed this game and found myself trying to master it. Great job!
