An excellent example of style over substance.
140 pulls its minimalist aesthetic off decently enough, but that's about the only positive thing that can be said about the game. The platforming gameplay is as shallow as one can imagine, your only actions consisting of jumping and moving (always at a fixed speed). Since the whole game revolves around stage hazards following musical rhythms, you always progress at the pace of the levels, waiting for the right time to advance. Boss fights are a little more interesting for deviating from the main game in different ways, though you are still a slave to the game's music-based mechanics in those.
Oh, and you can beat the main game in 1 hour. It's like, three stages long, and after the end you can replay mirrored versions of those same stages without checkpoints (you can't get much lazier than that with hard modes). That's about the entire game for you.
There's nothing broken about 140. It's just that it's boring, unfullfiling and has as much content as miss south carolina's skull. For the price it charges, you can get way more interesting games around gabe's funhouse.
