WASD to move Space to open shop E to open inventory, put the pointer over ammo and tools to see how much you have. Mouse click to shoot (what do you expect bruh). R to reload. Mouse Scroll to switch weapons.
I'm remaking this game, with room-based multiplayer, cosmetics, map editor, multiple gamemodes, AND MORE ZOMBIES!1!1 >:D. If you have any questions about the remake, make sure you ask me, i'll answer a soon as possible. At first i was going to make it with turbowarp, even though it removes most of scratch's limitations, and has even a networking extension, legit multiplayer was still extremely hard (there's no guide or manual, you gotta understand stuff by yourself), and also still has performance issues, i'll remake it again with Godot 2D, It's hard but balanced, I know i've been saying that i'll remake it for so long and did nothing, but from now on i'll start getting serious about it, and yeah that's it, thank you for reading. :)
