Space funeral is finally on itch.io. Probably because gamejolt sent many devs an email recently in december of 2021 stating that they are deleting games that are mature. Gamejolt then proceeded to take down everyones pages immediately then backtracked in January 2022 after emails of complaints and gave everyone more time to dispute such a claim or make an update to fans that the game will be removed.
Anyways, space funeral is one of the best games that I've ever played. I highly recommend. Give it a try.
