Good evening, I ran into a problem, but with the help of a tutorial and a colleague (thanks, @shatteredreality), I was able to solve it. I decided to share it on GitHub, to make it easier for others to build on it.
You can find it here.
No need to credit me, but please don’t claim it’s all yours if you don’t modify it. Also feel free to contribute anytime!
I’ve never hosted anything on itch.io before, actually. I thought it would be easier to do it through GitHub, since I have some experience with it. Besides, it’s not really an original project - I just followed a tutorial and made some small (not to say tiny) changes to the code. I don’t think it would be a good idea.
