TowerFall may have been focused on multiplayer mayhem, but developer Matt Thorson's next project looks like a different type of chaos. Celeste is a tough-as-nails 2D platformer a la Super Meatboy about the perils of climbing a mountain. No, not dealing with vertigo or rockslides, but slippery slopes and spike-filled pits. That's assuming the game follows the groundwork of the same-named prototype Thorson and co-developer Noel Berry put on the web in 2015. The game's out next year and really that's about all we know at this point. There's a cryptic GIF on the development blog, sure, but that isn't much to go by.
Despite its two-button control scheme, the web version of Celeste wasn't simple by any means so I don't expect the expanded version to be any different. As Rock, Paper, Shotgun notes, Interested mountain climbers can still check out that early version online.
