You bolt across a green field that looks exactly like the Mario you grew up with, hit that first floating block for a coin, and the ground vanishes beneath your feet for no reason at all. That's Unfair Mario, a precision platformer built entirely around traps you can't see coming until they've already flattened you. You run, jump, and weave through deceptively friendly levels where invisible spikes drop, hammers swing, and blocks crush you the second you trust them. Every death teaches you the layout, so you memorize, retry, and shave seconds off your run with cleaner inputs. Think you can clear a screen without dying once?
How to Play & Controls
- Move left and right with the Arrow Keys or A/D.
- Jump with Space, the Up Arrow, or W.
- Tap jump twice for a quick double-hop over surprise gaps.
Tips & Tricks
- Memorize where the invisible blocks sit so you stop jumping into dead air.
- Hang back a beat before crossing open ground to bait the hiden falling traps.
- Hug the lower path on crusher rooms to slip under the timing instead of over it.
