Impossible Castle

Impossible Castle is a simple Platformer in which you play the role of a knight, Grégoire Delabouillabaisse, trying to take back his castle from the hands of the terrible demon Mammon, but beware, his mere presence has corrupted the land, and now all sorts of creatures run rampant across your kingdom, will you be able to defeat them all and conquer this impossible castle ?

(please be nice this is my first game)
