While trying to port this game to Mac, I also ended up making a Windows build for testing that fixes the screen freeze issue and the resize issue: https://mega.nz/file/6NZA3KoI#rXKM0EpBQDNKIsPc7a2MOKGiiTb5CKV3eT0KF10dq2M
The resize fix restores the full screen behavior from other RPGMaker games, but this behavior doesn't actually render at a higher resolution, it just stretches the game area to fit the screen which makes things blurry. There are no RPGMaker games that support being rendered at different resolutions as far as I can tell.
I did, but I wasn't able to test it. You can try if out if you want: https://mega.nz/file/zMRQRKIK#ydTRUiUOK9M2PAvDLZ6Qk2mot_s1z9yNlxD91QCfPW8
I'm not sure if the packing method used by the Windows version is compatible with Wine anyways.
I based it on the Linux version, but a quick search yielded https://github.com/nanami5270/GARbro-Mod which seems to work for the Windows version.
No problem. For reference, it's not Electron that combines all the assets into a single file, it's Enigma Virtual Box. By default, Electron does no bundling of assets. This game uses both Electron and Enigma Virtual Box (On Windows).
