Carrion is probably only like ten hours worth of gameplay, but it's absolutely spectacular and if it had been significantly longer I think it might have started to get stale rather than being truly memorable. You play as an amorphous monster and start the game by escaping from your containment tank at a research facility. The core mechanics are barely explained to the player, if at all, so each new game mechanic is introduced alongside a puzzle that more or less amounts to understanding how to apply it in-game. I'm aware there are console versions of this game too, but the fluid feel of how your creature moves is such a huge part of enjoying the game that I have a lot of trouble imagining a gamepad could get that down anywhere near as well as using the mouse+keyboard. I love the touch that you grow with higher hp and movement becomes much more cumbersome, but you can get back to the more fluid movement by shedding hp. Also the map design is great, it's highly nonlinear and very easy to get lost. The only actual complaint I have is I didn't like hearing all the terrified screams from the researchers, but it's hard for me to picture a way around that without breaking the immersion.
Eastward is pixel graphics but when I tried it with wine I had some minor framerate issues, it can handle integrated graphics but how well will depend on how good your pc is. I played it on switch originally. I think the gameplay is enjoyable and done well, but it's not the reason you play the game and is not a game for someone who skips past dialogue whenever possible. I am not that someone though, and Eastward is one of my absolute favorite games I've ever played. The pixel art is gorgeous, characters and npcs have personalities you get attached to, soundtrack is both great music and matches the atmosphere, it's something special. The writing and dialogue are just wonderful, and combined with the pixel art there's so much emotion packed into it. At times it is uplifting and heartwarming, at other times unsettling and creepy. The change in tone when stumbling upon the factory in Greenberg caught me completely off-guard, just amazing. Only complaint was I spent most of the game excited to find out how they would tie all the loose-ends together and that never happened, there was a lot more left up to interpretation than I was expecting, which made the ending a massive disappointment for me.
Fallow is another short game that I personally really liked even though I didn't really understand it. There's not even a lot of gameplay in it, it creates a beautifully creepy atmosphere and the game is more or less that you sit in that and absorb it. It was an experience of observing a different world and trying to comprehend how that world works. I can't even tell if it was intentional that I didn't get it or if I'm just bad at media interpretation, but there's emotion in it either way.
Monster Sanctuary is a monster-taming game with a wholly uninspired story and mediocre pixel art, and both those issues made me give up on it after just a couple hours initially, but when I eventually gave it a second chance the gameplay itself is really engaging and well-designed. It's something I've come back to a few times since then just because of that. There's a lot of depth to it and it's fun to experiment with.
