I got a love-hate relationship with this game, its fun and satisfying but golly it is frustrating with unforgiving puzzles and even fewer check points. I only got to the second level, I couldn't get past the part where you had to do an off beat jump to reach the top. I'd suggest giving more room for error on some puzzles or alternatively, adding more check points. (not like putting one at every major puzzle, but at least some of them.)
To anyone reading this, play the Tutorial, its quick and it will come in handy sooner or later.
