Quite creative! Would've been grateful if there were more levels in the free version! But I'll probably buy the full version now I guess..
Level 8 I try to do it its not working
A very nice Brain teaser !
Cool I love it
Hate it Not working only a key
Fun puzzles with a difference I got through to level eight with relatively low stress on the brain cells, but now it keeps popping up with a box telling me to buy the full version. Not bad for a freebie but it really is only a trial for the full version.
