I have no idea if triangular noir-adventure Flatland: Fallen Angle was specifically inspired by 2011's meme-tastic Bastion, but I do suspect we're likely to see quite a few games that borrow its narrate-as-you-play mechanic over the next year or so. Flatland has that, albeit with a narrator who doesn't exactly offer the same gravitas as Bastion's Ruck, but it also has a guilt-wracked triangle on the run through a top-down, two-dimensional city, pursued by similarly pointy guards and in search of dark justice.
I tip every hat I have ever owned and ever will own to its title pun, too.
Made in just 96 hours (over the space of three weeks) it's very much a shortform piece and suffers from a slightly wobbly combat mechanic (death seems to come suddenly and randomly, but the idea is you can only cause damage by hitting an enemy with one of your points), but it's atmospheric, smart and does a great job of the unusual melange of simple line-art, breathless Pac Man-esque outrunning of foes and a doomy, nuanced narrative.
I really like the visual concept of the triangles splintering and fragmenting when they take damage too: it adds a real sense of desperation to the strange darting and spinning of the battles.
Entirely worth your time then, and your joining me in a hope that it can be expanded into something more fleshed out. It's free, but there is a $1 'appreciation version' with dev commentary and an arena skirmish mode, should you wish to provide it with a digital hug.
