Towerfall Ascension was too big for OUYA, so it jumped ship as soon as possible and brought its awesome local multiplayer to new platforms. Notably the PC and the PS4... the latter version falling foul of Brendan due to its lack of online multiplayer (by design) and rather expensive price tag. £11.99 was a little steep in fairness.
As always the PC version is much more competitive, though, especially now that the Humble Store have knocked an extra £3 off the asking price. Be aware that it's local multiplayer only, so you'll ideally want to have your PC set up on a living room HDTV with several controllers. Gameplay-wise, it's a little like Worms crossed with Super Smash Bros, only nothing like that whatsoever.
