While it's not exactly surprising, given the website this game originated from, the scoring system is designed to ensure that every player has virtually identical scores. The main point of differentiation between scores comes from nitpicky optimization of the timing of your moves. I don't find that to be compelling, from a gameplay perspective, because there isn't really much skill involved with this. Rather, you score well by repeating the otherwise simple puzzles again and again and again.
Other than that, the game feels cute, overall.
Good game..but was so easy!
One star for hijacking my right-click menu and not giving me a graphics quality toggle. That's ludicrous and annoying--and it needs to stop. Leave my right-click menu alone.
