You were Coding on Scratch, when, your "Minecraft Boss" project got corrupted. After trying to resolve the issue, you found yourself inside the computer's code as it's resetting itself. Now you must stop whatever is causing this before your files are deleted! WASD/Arrow Keys to move Z/M to slow down Space when you have an egg to throw it. Be sure to time it correctly, or else you'll miss! Hold L to skip through the opening monologue. The boss takes a total of 6 hits to defeat, if I counted correctly.
Posr made the original project and asked someone to make a hard mode. I'd say the monkey's paw has done its work. I pilfered some scripts from Ggenie's Scratch Tips project.
