so someone suggested that I restrict the executables behind a code on the project page
What would that accomplish?
This is Itch. Just upload the experimental downloadable of your web game as a a downloadable file to your web game. And state clearly, that there was not much testing done.
But you do have a machine to test the executeable and give it a play, do you not? What type of unique issue are you expecting? Your playtime is stated as half an hour. Can't you play for half an hour and tell if your computer is on fire after that? Is that about the android export? Why do you need one? Does the game not run on browser on an android device?
Oh, and maybe do not make a devlog every day. It's pointless. Also, why do you add a file to the devlog, if you are having currently a web only game?
