there was a fedi shitstorm recently RE: centralized blocklists so I tried my hand at a web service that would facilitate aggregating and sharing these lists in a decentralized and dynamic fashion and so far I like how it’s coming along

I’m hoping to build a frontend for it soon-ish

Godot should work, as some have suggested.

Failing that, I would strongly recommend you become a little more familiar with coding so you can take a look at multimedia libraries such as SDL, Allegro and SFML.

Even if Godot works for you (it really should, I use it with my laptop with 16 gigs of ram but no dedicated graphics), you will absolutely need to be comfortable with coding to write your game scripts (basically your game’s behavior) in GDScript, Godot’s scripting language.
