Glad you like it! Thank you very much!
The game has a maximum score value. Because otherwise the hiscore table would be not as challenging as it is now. If you replay a level the score of this level is reset until you have collected all diamonds in the level. To ensure that there is a maximum score I had two options:
1. reset the diamonds if you replay the level even if you had collected them all.
2. make the diamonds uncollectible.
I decided that option 1 is too nasty. Especially in the really hard levels this would be like a punishment and prevent players from replaying a level just for fun. Beat level 13, and check your own opinion about that
Android version: I'm not sure at the moment. I'm debating this with myself in the next weeks
But, did you realize that you can play it already on android in the browser?
