Hey! Thank you for reaching out.
It took some time, as we use Unreal Engine and also 2 external middleware tools that needed fixing to make Linux build possible. But it seems I will be able to proceed now. Unfortunately I can't update the builds on Itch.io during the Jam. I will surely upload it after the voting ends, but if you want to play it early and be able to rate us I will gladly send you the build when it's (hopefully) ready. Just reach out to me on discord -> nickada on the Black Cat Jam! server.
