Quality assurance would be great! Cloning the repo, and playing around a bit with the code, like adding in a jump, or adding in a menu, or anything you fancy, should be very easy. If it's not easy, it would be great to hear about it!
Example game, something simple that can be picked apart easily. There is currently a PR (#13) with a start, and I've tried to keep it simple, but it's hard to know what is needed and how complex things should be. But trying it out and seeing if small changes can make the code better, we can maybe get something more interesting. Because it's very much just a shell of a game at the moment.
Looking at the PR and the code. The more eyes that are on it, the better the end result. if you find a typo, fix it and make a PR, it's worth it's weight in gold! (PRs are pretty light)
Alternatively make these into seperate issues so they can be resolved by a PR each.
