Good game. Would like an option to turn off the enemies though because while I like the puzzle element the enemy placement and movement is quite annoying as it seems totally random and jumps character squares at a time . I spend a lot of time not moving waiting for an enemy to move out of a space I need to move in to and it can take several minutes! Also noticed a small bug. If your sd card is read only program will crash when trying to save.

Very nice, like it!
