Raw Metal: A blend of top-down stealth and SIFU-like 3D brawling presented in a very stylish package. You sneak through mines gathering resources and taking down guards. When you encounter a guard, the game switches to 3rd person over the shoulder and you get to the usual hit/dodge/parry. Very fun, but it has a bit of a learning curve.
Rotwood: Co-op roguelite beat em up. Nice art style and the combat is chunky. Didn't try the co-op part because I don't have any frie- Everyone was busy. Fun if a little simple.
Children of the Sun: Puzzle sniper. You pick an angle, mark your targets and shoot. The next shot is taken from where your last bullet hit, kind of like golf in a sense. The base concept itself is pretty fun, and then the game adds a few more mechanics on top to make it even more interesting. Good stuff.
#BLUD: Action RPG with a very cute Gendy Tartakovsky art style. It takes such heavy inspiration from him that the main character lives in Dexter's house. You fight vampires in a little suburban town. Pretty fun. The main draw here is the world and the feeling of being in a cartoon. Slow start. Lots of talking and world building. The game drips SOUL like a broken faucet.
Berserk Boy: 2D action platformer that takes VERY HEAVY inspiration from Megaman Zero. Dashing around the levels feels very smooth. A bit too easy, imo.
Other stuff that I tried that has been mentioned:
Maniac: a chaotic GTA survival game. Surprised it took so long for someone to make a standalone game using GTA's most fun aspect.
Pepper Grinder: Delightful. One to look out for.
Guards!: A co-op game where you play as medieval guards and you arrest people. Didn't play it much since the game has no tutorial and I had no idea what was going on.
Artifact Seeker: A chinese knockoff of Vampire Survivors but roguelite and with more numbers. Braindead game. You get a ton of items and stats thrown at you that make no discernible impact on the gameplay. Do you want +0.02% crit damage on a skill with a -1% movement speed penalty? It has Shatter and Freeze synergies. What does any of that matter? Well you see nigger nigger nigger nigger nigger nigger.
