Hello, this is an unfinished finished as I would have loved to put much more elements in this game. 

Instructions to play this game (as I forgot to add):

W,A,S,D : to move

Space : to jump

Left-click (mouse-button): to fire orbs

You can move your mouse to aim at the enemies with your mouse.

Goal:

Defeat all enemies and you win!!

Press 'R' to restart the level if you want

I hope you enjoy it ! :))
