5 second to prepare at the start btw you have 10 health E to fire, the more you maintain the button, the more it has precision, and at max precision, it can perce SPACE to slap with sword, cooldown of 15 sec Q to heal, 5.5 health(take time before it actually heal), cooldown of 30 sec wasd or arrow to more, ws and up/down, more, ad and left/right to turn
Based on MY many other games (NOT FINISHED, ITS JUST A FORETASTE OF MY GAME) Imma try to do(working on): reload/ammo, better back ground , more different zombies, more weapons, cooldown idex/just a place where you see the cooldown of abilities, and more(pls give me ideas)
