Yeah I know, I got into a rut after this, so I have no idea what to do. I should not have made my own physics engine, but even then, I still can't find any I can use with my project.
I may come back to this months in the future, or years, or even decades if necessary.
But I do plan to come back again, even if it's only to say thank you for your support, and officially end the project.
On that note though:
Thank you to everyone who helped me and/or tried out my game, it means the world to me. Making this game was very much a learning experience for me, and gave me good knowledge of the C and C++ language. And I will always remember this fondly as my first true project.
