Bug: I'm told to disobey 'pressing THIS button'. I don't press it, but I also don't press 'THAT button', logic tells - I'm supposed to pass - yet, it counts as fail.
Imo, This game is poorly developed.
Creator should make sure, every REPEAT of level is mathematically possible. From my observations (mainly 1st level & balls) are not passable for big amount of cases. I couldn't spot any communicate about epilepsy, but it might be my oversight. I don't understand how anyone, who played insane mode could be rating it more than 2.
P.S. Done dragon with power, but range is easy mode. Difference is - If somehow (impossible, but might happen) you die on range mode, you'll have to reclean act 3.
