Not bad, but not great either.
First, I was geeked to see this game. I've always been a fan of puzzles like this. And really, I wanted to love this game. The first few levels weren't too bad and all was fine. Like another reviewer though, I found myself stuck on more than one occasion - not because I couldn't figure the puzzle out, but because the block needed to be moved a millimeter further than I had done it. The first time I laughed at myself, but the by the 10th time of this happening it was frustrating. The controls themselves weren't that great and I think it would be better to have an option to click on in order to choose which direction you wanted to move the block (ie: horizontally, vertically, etc) rather than fighting with the blasted arrow thing. The space bar bit got mildly annoying and, for me at least, I found that the tool would switch back and forth seemingly at random. I'm sure I was doing something to make this happen, but I never did figure out what it was. Also, and this isn't a complaint but more of an observation, but don't bother playing this with a laptop track pad. Thankfully it saves because I restarted levels more than once because a slip of the hand which resulted in clicking on a link outside the game.
My only other critique would just be the puzzles themselves. Same as before, they started off great, but the final few were less puzzle and more "randomly move blocks and hope it works" because you actually can't see what it is you're trying to solve. The puzzles are on the inside and you end up trying to move the pieces around until you get lucky in some cases. Still, there are some great ones in there that required a lot of brain power to work around and are quite clever.
I really hope there's a second one and these little things are addressed. Really, it's just issues with sensitivity I think and the controls and how you're using them. With a couple tweaks, I think this could be an excellent game.
