this is a school project i made W to attack (almost no cool-down) D to heal (would be impossible without) ? to use Boss Buster (helpful for the final boss. not so much on regular enemies, unlocked after first level) ? to use Enemy Eraser (late game enemies will be defeated easier with this, not so much bosses. unlocked after 2nd level)
There is a lot to credit, i'll make sure to do it later there is a bug that if an enemy is below 0 hp it will not die, idk how to fix this.
