I love the purity of 10 Second Ninja. It's a unique, simple concept executed without fuss: you have 10 seconds to clear a nightmarish level of platforms (opens in new tab), traps and baddies. Go. Technically you can complete the game's 40 levels in just shy of seven minutes—but you won't.
10 Second Ninja X is a sequel and remaster all in one, featuring a set of 60 new panic-inducing levels which, once beaten, unlock the original 40 levels remastered in 1080p.
There's also a new story that is, erm, allowed in Germany this time. 10 Second Ninja's Robo-Hitler was not deemed an acceptable boss. Joining that is a marathon mode which will feature each area's levels stuck back-to-back for the best in speedrunner bait (opens in new tab).
We're told to expect it some time in summer.
