with all the high praise in these comments I wish I could've played it, but both the browser and downloaded version are stuck on the title screen.
...is what I would've written if I didn't figure out (after more time than I'm willing to admit) that I had to press spacebar to move on to the main menu.
And now that I've played it, this is a lot of fun to play, gotta agree with the others here. My only complaint is that I can't put small tiles close to the wall. I love the music choice, the little animations and texts the little character does, it's great.
