Coil doesn't really feel like a game. It's a collection of barebones minigames that paints an interesting story, but not much else. It takes about ~10 minutes to complete but it was pretty boring to play. Not much to say, honestly.
Really weird and I didn't like it very much- almost no gameplay and a narrative that I don't like. it's incredibly short though, so I can't complain too much.
Only really worth playing if you're playing it through The Basement Collection. That is, if you're trying to unlock AVGM. Other than that, it's just a really average, artsy-kinda game. Not necessarily a bad game, though.
