First of all, thank you for playing and sorry for the problem of the sensibility, we didn't had the problem in our computers :(
If we update the game we will add an option menu and a sensibility settings
This is a jam game (made under 48-72 hours) thats why the game don't have a tutorial, but the same that the sensibility options, we will update the game with a tutorial to have a clear understanding how to do the craftings and how to play "correct" the game. At the moment I only can say that checkout the shop to see how the things are ordered and check out the posters around the shop with the instructions of the game.
Thanks for the feedback ^^
