I'm gonna be honest, OP. The way you're doing this is going to be a VERY tough sell to basically everyone.
It's already difficult to understand what your game even is, and then when you add the fact that it's only available from time-limited download links embedded in obscure Lemmy threads... let's just say I'd feel more comfortable downloading software from a URL I found scrawled on the wall of a gas station bathroom than whatever it is you're doing.
You say that the code you wrote is "really easy to check", but where? It's not hosted on a public repo, so the only way for people to audit your code is by downloading your "game", which, again, is a tough sell when it could be literally anything.
If it walks like malware and it talks like malware...
