Project B comment:
The first few text boxes are little redundant I would say since there is only one way forward. After collecting two of the crystals I felt like I already tried everthing and didnt know how to progress. The part with the jump for the shoes is way too hidden and I dont think its actually possible to figure out on your own (maybe I just missed some clues).
Overall its quite fun fast and easy game and the bigger jump feels cool. I only managed to find 2 crystals so If I had more time I would try to find them all.
