Press e for a permanent shield (it cost 30 mana forever) and press q for a laser (it cost 100000 mana but it does a LOT of damage, and don't use it at the start because you will get negative mana) and the default attack is the space button, press f for shield attack (it cost 35 mana btw), press g for deflecting the enemy's magic (it's inaccurate compared to the original video I tried my best), also the green thing is the heal and mana (just so you don't die as I tested, there is a bug that makes you die for no reason), and added music
thx to @Thegamer7777 and @Giovanni429 and thx to @Time_God for the Overseer sprite (did I add too many changes?)
