I'm sorry, no other person has reported such a problem yet, it might be in your end... do tell us if you manage to fix the problem on your side please, might help us with future updates.
Just a quick heads-up: the game works fine when downloaded from the browser, but the itch.io app can’t install it and shows “No compatible downloads were found.”
It seems the client doesn’t recognize the Windows build, so updates can’t be handled automatically.
Probably to fix it, you just need to:
1 : Go to your game’s edit page
2 : Scroll to the “Uploads” section
3 : Click the gear icon next to the Windows ZIP
4 : Enable “This file is a playable build”
5 : Set the platform to Windows
(or at least that's what I found on various itch forums)
Not a big issue, but wanted to let you know in case you want to make it installable through the itch app too. Thanks for the game! 😊
