Grimace Only Up!

One wrong jump sends you tumbling all the way down—how high can you climb before your nerves give out?

Grimace Only Up! strips the climb to its raw nerve: you're a purple lump with legs, staring up at a sky-high stack of floating platforms, tires, pipes, and bits of geometry that couldn't care less if you fall. WASD moves you, space jumps, and that's the whole toolkit. No double jump, no wall climb, no mercy. The first few ledges feel tame. Then you hit the rotating drum, the narrow vent, the moving platform that lines up perfectly right until you commit to the jump. I lost a twenty-minute run to a single mis-timed spacebar press and actually shouted at my screen. The real beast here is the lack of checkpoints. Fall from any height and you're back at the bottom, watching your progress mock you from above. Some players will rage-quit in the first ten minutes; others will get that weird itch to try one more time because they spotted a shortcut. Yes, there are actual shortcuts—skipping a whole section by bouncing off a random tire feels like cheating the system, and that's the best feeling. The hitboxes are slightly forgiving on the edges, which you'll learn to abuse when your toe catches a platform that should have let you slip. Grimace himself is a weirdly endearing mascot for this kind of suffering. No dialogue, no story, just a determined purple shape ascending into the void. The background shifts subtly as you climb, which gives a nice sense of vertical progress even though you're terrified of looking down. If you want a challenge that respects your time in the worst possible way, this one's a nasty little gift.

WASD control the character, SPACE jump

Treat every jump as a commitment—hesitating mid-air kills momentum and accuracy. Use the edge forgiveness: aim to land with only a sliver of your feet on the platform, it's more reliable than it looks. Scout the rotating obstacles for two full cycles before moving; their timing is consistent but only if you watch, not guess. If you find a shortcut that involves bouncing off a tire or vent, practice it at low height before betting a whole run on it. Keep your camera angle fixed or reset it often; a tilted view ruins your distance perception on narrow beams. When you fall, don't immediately restart—watch where you land, sometimes there's a lower path you missed.
