The simplistic artstyle and cover betrays how good this game is. The controls are floaty sure, they could use a notch up on gravity but the platforming is solid, the wall jump specially and the platform placing mixed with the slow mo.
The level design is king in this game, its simple but elegant in implementation; at all times you know what to do its just a matter of doing it and the mix and match of different well implemented elements of the level. The variety found in this game means that you go from situation from situation completely engaged and wondering whats coming next.
Theme, as mentioned it does the only one platform and its front and center in every situation.
Originality, the one platform thing has been done a lot but not in this way and for sure not this well implemented.
A good surprise and a cautionary tale about not judging a game by its cover.
