I added a fullscreen button to the page. I think your game is really cool! it's got cool mechanics that are incorporated into the levels quite nicely. One thing though, is that the player probably shouldn't be a full tile wide so it's easier to fit into one tile gaps.
Thanks for the great feedback! I've already added some obstacles, I just need to add them to levels, but gravity based level components is a great idea!
My first time making a puzzle game, if any of you guys could help me make some more levels or improve the three I have right now it would be greatly appreciated!
Looks really cool, I think adding some iframes might make it more fun to play. I would get trapped between an enemy and a wall and just die immediately. Other than that, really cool game! also i agree with the other guy that throwing tons of gears at once it really fun
