It's not the kind of game I usually play but it's well playable.
On the moment I didn't understand that cube give you a second jump (you should explain it in a tuto for exemple) .
Thanks for all your comments. This game was a kind of test. I wanted to know if it could be appreciated. So I think I'm going to do other episodes when i'll have time. Perhaps in other ages (knight, streamPunk ...) but always with Stachmou.
