========================================== wasd to move r to heal 1/2 to switch between melee and ranged and then when on 1 for melee space bar swaps weapons (knife, scythe, sword, axe) each with a custom attack, then E is a fire blast and Q is an explosion both of these however require mana of which the higher the level you are, see top left corner the quicker it is regained. Then to heal you press R and to summon the boss once you have all 4 artifacts which are dotted around the map when you see the red symbol you press G to sumon the boss. =========================================
Thanks to -OctoLegend- for the original collision engine he lent me for an earlier game that I've repurposed for this game.
