Ok first off PEOPLE HAVING TROUBLE WITH BOSSES HOLD DOWN THE MOUSE BUTTON!
so i was going to give you guys a pretty bad rating because i thought your boss battles were glitchy, until i made it to the shirtless transporting shredder guy, I wish that holding the button part of game play would have been in large flashing letters at some point. There were a couple glitchs, like not being able to transform occasionally with spacebar. Once or twice I would hit the spacebar, not tranform, and just move up with every tap. Beyond those bits great game, good lil puzzles fun achivements, great graphics! and the music is pretty good. I just wish you would have been a little more clear with your instructions.
