A very nice game, similar to another entry (COGS), but with its own great ideas. The lasers we have to desactivate are very interesting for a level design point of view, love it!
My only grief is that it's sometimes a bit hard to understand where I can place the gears. Visually it seems OK, but for some reason the gear refuses to stay in place and disappears. Because of that I'm blocked in level 5, but I would love to see more of your game!
