Maybe you can try starting the game through the itch.io app, it seems like a lot of games that have been "unsigned" like mine have the same issue, caused by the macOS Gatekeeper.
I already recieved some good words of advice from the community. Apparently, releasing source code without a licence does not make it open source by default.
I requested a DMCA takedown, and I will release the official version on Google play, without ads or micro transactions.
