Ten Ton Ninja is a simple game, without great features, that has a retro feel in the purest style of the old platform games from the 1990s.
In Ten Ton Ninja you have to get through 22 levels with the usual elements of platform games (although it has a lot of stuff from arcade games too) where you have to get past dangers and advance through the levels.
The most interesting thing about Ten Ton Ninja, without doubt, is that it comes with its own level editor, so you can create your own totally personalized levels, then you can share them with other users of this game.
