Blue Player:
-ZQSD to move, Jump and "dash" to the ground (You can change you keyboard to AZERTY in the Windows settings to use WASD if your keyboard is a QWERTY)
-Space barre to uses the Attacks
Red Player:
-The Directional Arrows to move, Jump and "dash" to the ground
-0 (insert) to uses the Attacks
Attacks with a S because you can use a Charged Attacks moreover the simple one by keep the Attacks key pressed and releasing it at the good moment and use a falling attack by attacking while... Falling.
If you want me to change the attack key, just leave a comment about it with the key you think better. Especialy for the Red Player, I was wondering to putg the Attacks key on CTRl Left for him but, if you want to play with 2 hands, it would have been impossible.
