Cool. I feel weird comparing this to the Bonte games, but I enjoy how it's still the same goal in a sense but the mechanics differ each time. They're not simply clones of each other.
This was... INFURIATING. A good difficulty level is putting goals (or checkpoints here) juuuust frequently enough for the player to feel challenged without being frustrated. I. Was frustrated. IMMENSELY. Screw this. I earned the badge and yes it earns its status as "hard". Who hurt you, Ferociter?
10 makes no sense - there is an odd number of squares so you will be left with one blank space. If I have to look up a walkthrough 1/5 of the way through the game, then it makes no sense.
And the levels are a different order for the android game. This is stupid.
