Octohedron is an incredible pure-platforming challenge designed with endless creativity.  Each level plays with a new theme, exploring its possibilities from an initial easy tutorial moment all the way through to lightly sadistic at the end, with plenty of room for play in the middle.  Finding all the secrets of each level can be a mini-quest that takes several playthroughs to unravel and some of the hiding spots for the triangles are downright devious.

Still, Octahedron is a great platformer. Though I did have some issues with the presentation, the checkpointing, and the sometimes crushing difficulty of later levels, that never dampened the joy I felt in those precious moments when I finally clicked with a stage I'd been struggling with for hours and made it safely to the exit.

The game’s narrative is far dourer than the 80s neon electro-synth aesthetic you spend most of your time in, but it is certainly mechanically satisfying enough to run through the whole thing more than once – and I found myself looking up the soundtrack long after I’d had my fill of the game itself. There is definitely a lot of thought and passion that went into this, and if you are a fan of 2D platformers, there’s no reason you shouldn’t check this out.
