Heyo, thank you, glad to hear it!
Have you tried itch's launcher to download the game? I am pretty confident you can then launch it offline anytime you want to
Yes, I did try that out, but I was actually thinking that if we could have an offline build maybe we could port it to retro handhelds like TrimUI Brick with portmaster.
Another option would be to port it to gba (like for example, celeste classic and balatro) and almost any device can run it through emulation.
Do you by any chance have plans for porting? (I do understand that it could be somewhat difficult 😅)
