Answer 2

Well, I've seen card games, snake games, platformer games, etc. There are a ton of options.

This is something I've been working on: https://code.sololearn.com/WQU8o8PHedlL
It's a 2d platformer made with Javascript. Right now, it only works on a computer and the test level is rather small, but I'm slowly expanding upon it.

I've also made a pong game on my profile, so there really are a ton of options!
