Thanks, be sure to check out some of the youtube videos for the full version. The levels get more graphical in the higher levels. The full version has 4 more levels right now, but I am preparing to release 2 more in the next day or two. There are 10 more planned for no later than the middle of next year, beyond that it depends on interest.
I never though I'd criticise a flash game for having a bad map, although now I have to do it. I'm not like other people - I'd honestly prefer a linear map, or at least a mini map. This game kinda confused me after level 4. It's a good game, and I'll carry on playing it, although it's hard. 4/5.
