I’m just about to sit down and play a bunch of these demos (I downloaded like 30+ of them earlier!) but I did check out a couple that I haven’t seen mentioned here yet.
Hellscreen - a first-person shooter with an intense visual style and unique mechanics. The main theme about this game that’s a bit brain-bending is that at all times at the top of the screen is what is essentially a rearview mirror. It’s primarily there so you can see behind you when you’re getting swarmed by enemies but in the first handful of levels there’re a bunch of different uses for it too. Such as: certain enemies/pathways only being visible in the mirror and the mirror being your only source of unobscured vision when you’re in complete darkness. Super neat idea but I thought it was extremely disorienting!
GRAPPIN - a first-person platformer where you move around with a grappling hook. Normally these kinds of games are high-octane action but this game is so much more chill than I was expecting it to be. Although you can fling yourself around with different kinds of grappling hooks, the game emphasizes taking things slow since you’re also meant to explore the environment to find hidden items to unlock gates.
Anger Foot - an intense first-person shooter with lots of foot-based action. I was expecting the mechanics to be fairly basic or one-note but after messing with this one for a while and trying out the different shoes (abilities) you can unlock, turns out this game’s super sick. Most interesting part of the game for me though is the music during the levels. It’s all modern gabber and it seems to be either a bunch of random tracks or generated by some other means. The way it alternates between being “on” or “off” depending on whether or not you’re engaged with enemies is extremely propulsive and compelling.
Last Command - a game where you play as a sentient computer program in a post-human world (I think?). The gameplay in this is pretty unusual but it’s basically like if Snake (the classic Nokia game) was entirely made of bullet hell-adjacent boss fights. The dots you collect turn into bullets that you can fire at the bosses heart, which is an interactable object on the field, which fills a percentage meter. When you fill that meter you attack the heart by dashing into it and move onto the next phase of the boss.
It’s quite a lot to take in but once I figured out how to put all the individual pieces together it was exceptionally thrilling.
