Sorry for replying so late! Thank you all for the responses. It seems like a system of acceleration and damping rather than straight up friction would be much better-suited for this game.

Hey guys, I've been having a lot of problems lately conceptualizing platformer friction. I've watched several Khan Academy videos to refresh my knowledge on the subject, and I have a pretty good fundamental grasp on friction, but my problem is in "gamifying" it, if that makes any sense. Si...

Dude. You're 15, and you made this? I'm looking at the source files, and wow, I can't even fathom having that much gamedev/programming knowledge at that age. Seriously, bravo, man.

Wow, you guys are doing some seriously impressive stuff :O I basically just started learning LOVE a couple weeks ago, but I still haven't gotten too far. I've been hung up on figuring out how to make a platformer with vector movement, but it's proving to be a bit of a challenge for my first project....
