39 should've been the 40 :)
had to deduct 1 star for the simple fact that sometime the computer moves to a spot where you can't possibly win the level and have to hope that the next time they move in a different way... i can't remember how many time i played level 35 where i kept getting blocked til the CPU finally put himself in danger and i was able to capture him. great work and loads of fun to play around in... you might consider releasing a level editor so we on NG can play some more with it ..cheers!
