I've got something cool now. I was able to implement enemy knock-ups. Also, I added damage, and with it, I added a damage knockback. Uploading the new version now!

Shift and rmb have a use in the game now, so we have 2 combos now.

LMB LMB LMB = normal projectile combo

LMB LMB RMB = knock-up combo

Shift = Dash
