It's a great game packaged in a really small box.
First and foremost, I must applaud you for making a game of this standard while not even pushing 300kb which is pretty awesome.
The Good:
- Small size - It's rare to find games of this quality
- Long lasting - I only finished the game after a good half hour
- Unique gameplay - Never before have I seen a game like this one
- Reasonable amount of levels - Any more and it would get boring, any less and it would be too short
- Simple interface - This is great since a puzzle game should not be too flashy
My Criticisms:
- No music - Music would've enhanced the puzzling atmosphere of the game
- Uneven difficulty - I must admit that levels 5 and 6 are much harder than 8 or 9
- Mochi Integration - I did not have a Mochi account, so I could not access the full game. This wouldn't had mattered on a site where it was very likely that players had Mochi, but on a site like Newgrounds where perhaps a minority have Mochi, it would have been best to leave out this feature and just allowed free access to the other levels.
Overall
For me, this was a very enjoyable, new experience and I wish to see more good work from you.
