Plain and simple its a good addition to the genre: frustrating and fun as intended. I wish there were some more ways to feel rewarded for figuring out a mechanic/trick. Ex: arrows that the player learns always point in the wrong direction or certain types of platforms that are always dummies. Getting lost is sometimes frustrating since its hard to differentiate between making the wrong move and going the wrong way. Also could use a bit of a more robust story and thematic consistency amongst the sprites.
