BONUS TOMT:
I'm looking for the name of a FLOSS Quake1-mod, puzzle game, that was about placing gravity points, to curve a stream of particles around the level, and eventually into the goal target. (May have used irrlicht)
If anyone knows the name of this one, please let me know, it is my white-whale of games.
My favorite is !dcss@lemmy.ml. ๐
Gameplay is similar to Shattered Pixel Dungeon, i.e. traditional roguelike, almost like a puzzle game. It is a bit harder to get into, though.
Just gave Dungeon Crawl Stone Soup another try just then, it is one that I will need a lot of beginner videos too.
Yeah, I had to start out with videos, too. It's certainly not a small amount of information to take in...
