My god, this game had everything, I laughed, I screamed, I cried, I felt joy and anger! The systems so simple, yet so effective and II haven't seen anything like that yet. Especially the level design was fantastic! Maybe fantastic is not the right word, more like diabolical! Those cursed magic balls placed in such a way to cause the most frustration possible, truly ingenious! At the end maybe there could've been more of an end screen, but nonetheless one of my favorite entries so far!
Oh yes: One additional piece of feedback from me: You control the kid by pointing your mouse right? Depending in which direction of the kid the mouse is located, right? So the kid is basically the reference point. However, when jumping the position of the kid on the screen moves as well - the reference point moves! I know for most platformers you don't want your character to be static in the middle of the screen and maybe I am completely wrong, but for this type of control system I think having the kid stay at one position on screen would make the controls a little bit easier.
