Hello, I am interested on your project, I have worked with the Unity engine extensively, I'm new on this site, so at least an opportunity would be appreciated, I can start working now.
By "Create a few variables" I'm assuming you mean a singleton that contains data from a file, or something along those lines, or maybe you want custom data structures, I can't be sure, so, please message me to discuss the details of the project, then I can say whether or not I can do it and how much I could take.
I will make unlimited revisions without extra cost, and will provide assistance with any relevant files for at least a week, and if you end up deciding that my work is not good enough or that it is not fitting for your project, that's fine, you won't have to pay me -although, an small amount would be very much appreciated, but I reiterate, it is not necessary.
Regardless of whether or not you award me the project, thanks for reading, and have a nice day!
