Challenging yet fun and pretty
Well, first of all, you must be amazingly smart to create those puzzles (or take them from somewhere) but anyway, the puzzles where easy to understand and very difficult to accomplish making it real challenging. The music made it kind of sinister or spooky or whatever but it fits well to the game and the visuals are pretty cool.
It would be better with an actual storyline and if it were longer.
I wouldn't recommend playig it if you have no pacience, you really would NOT enjoy it. Still loved it myself though. 5/5
