About this Mod
Deadly Jump — The Ultimate Hardcore Challenge for Your Game!
Think you are a survival expert? Have you beaten the game with no armor or just half a heart? Forget all of that. This mod introduces only one simple, yet completely ruthless rule that will turn your entire world upside down: IF YOU PRESS THE SPACEBAR, YOU DIE INSTANTLY!
Jumping is a natural reflex for every gamer. We jump while running, climbing hills, or dodging monsters. This mod turns your own muscle memory into your worst enemy. One accidental click, and your game is over.

• Strict zero-jump policy: No mercy. If your feet leave the ground by your own will, you go straight to the game-over screen.
• A whole new world logic: Every single block or tiny ledge now becomes an impassable wall.
• Crafting is your savior: Ladders, slabs, and scaffolding will become your best friends. You cannot even get out of a cave without them.
• No more shortcuts: Forget straight paths. To cross a mountain, you must search for natural slopes or spend lots of resources building safe walkways.
Can you beat the game and defeat the final bosses without jumping even once? Do you have the self-control to watch every single step you take? Install the mod now and test your patience!
