Just incredible, visually and musically excellently done. The American cartoon style of the 1930s and jazz go very well with this sublime, lively and nervous gameplay.

Regarding the difficulty, it is very well managed, the game is demanding but never unfair, when we fail it's always our fault, so if you think the game is too hard for you, do it on normal difficulty enjoy it anyway, although the game is obviously much more enjoyable in expert mode.

As for the price, of 20€ (not counting the promotions which are frequent), it is really very acceptable for this 2D platformer which is personally my favorite.
In short, a nugget to which it is absolutely necessary to play, you will not regret.

I find that I made a superb purchase which and very very nice I advise it really good delusions.
