Everything is done well. The gameplay mechanic is a great idea that is well-executed, the simple visuals are great, the sound and music are good, and even the vague text before the levels makes them feel more important. The levels are mostly well-designed although I struggled with level 7 (is the solution actually to race to the left side and climb up?) and level 9 (I spent so long trying to find the Knowledge, I even tried to jump to the left to see if the screen would wrap around, lol)
phenomenomal, my first perfect rating so far.
