I like the box-counting and row/column highlighting. It really needs hotkeys for each colour though, and one for a blank square. Also some of the art is.... let's just say weird. o.O
@Mermoofmer: There are some keyboard shortcuts, but discovering them is trial and error. For example, "F" goes to fullscreen mode. I haven't seen anywhere that the shortcuts are specified, though.
hahaha this is so cute! I played again and let the timer run out on each stage so I could see the funny fails. Definitely worth it :) I wish there was better music though >_<
Interesting concept, but poorly executed. I don't see the point of having a timer at all. Checkmarks should appear on both sides. A mute button is nice, but better music would be nicer.
stuck on the level with the corner building and the parked cars. Can't get the last one. Also the right photo is out of focus... How does that happen if you're working from the same image? o.O I liked the piano music though.
