I believe another one of their goals was to grow neurons out of their own human cells and then see who in the lab has the neurons most capable of playing doom. Or maybe verse each other in quake and see whose neurons win.
Gunpoint. Story based detective game where you solve a murder. Gameplay mechanics make you feel like a badass. You can pretty much finish it in a single sitting but its great.
Heat signature. A stealth based top down bounty hunter game with roguelike elements. Really well done. Made by the same guy that made Gunpoint.
Neo scavenger. A murder hobo roguelike with a surprisingly long storyline.
Super house of dead ninjas. Great fast paced platformer where you’re a badass ninja. Great to pick up and play in short bursts.
Fez. 2D exploration platformer with to change the perspective. Pretty chill and has a cool art style
More well known games that I’ll list anyway in case someones looking for some awesome ones:
Super meat boy
Project zomboid
FTL
Celeste
Crypt of the necrodancer
Enter the gungeon
Spelunky
Noita. Saw it mentionned in this thread and I am seconding this. Great game. But brutal as fuck.
Cave story. A classic. And it’s free.
Owlboy. Took the developer like 10-15 years to make. I’ve heard good things but I’m only just starting to play it.
Also pro tip: if you want more recommendations go look at what speedrunners are playing. People that spend that much time playing a single game over and over generally choose very good games to play.
