Hi and thanks for your comments. I have now made some improvements to the game and the problems with your first two comments should be fixed. The last one is more difficult. The button is for leaderboard and for some reason it sometimes work but sometimes it doesn't! I have not yet found what's the problem with my LootLocker scripts.
They game should be a bit easier now if you would like to try it again later. And it's easier to score points too! So you would have a good chance to top your own highscore.
