Great idea, great start, kids (3 & 4) are excited to play - didn't want to go to bed.<p>A few bugs, like a misplaced arrow sometimes can't be moved any more.<p>Please make clear why a level failed! The board just kinda disappears the moment the "program" "crashes".<p>One big recurring issue with games for toddlers: make it very tolerant of multiple touches. Kids often will touch other fingers to the screen, lean side of hand on it, or put other hand on. Try to identify which touch point is the "real" one and focus on that, ignoring others.<p>Great job! Looking forward to how far the kids take this. Several times a day they ask for "ghost game" (DragonBox, which starts with a ghost as a logo); they'll be asking for this one too.
