It’s fine to do new exports and important bug fixes after submissions close, I asked Sam :). Just don’t take the micky and add new gameplay as a “bug fix”
Edit: oh I see itch has disabled uploads so maybe not. Share build on discord?
Sorry for the late reply, wanted to test it on a virtual machine or a booted usb to make sure the linux export was working fine but haven't found time to do it.
(and servers are down right now...)
Hope it works fine 😥
