Customer Reviews

Good, but...

What this game needs is a local high score, so I have the motivation to beat my own high score. Otherwise, game is decent considering it is open source.

Love It

It took me a while to get used to it, but now I'm addicted to this game. Although, with a high score only in 200s I'm wondering if the leaderboard is particularly accurate.

Fun, but I expect more

I wish the graphics were better. That's pretty much the only problem with the game. The features are great, though.
