if you still have it in your steam library from years and years ago...its only good on your pc. They drop it....the saves etc from steam deck support after its wiped from the net and is up for freeware. Basically...the game is no longer acceptable or profitable for Steam so it has no place on the deck and they wont save our games that are considered "unacceptable". This has a lot to do with the interest level and how proactive the dev is in their games. If they abandon them, stop doing updates, or do anything that Valve sees as icky....it gets wiped. But since you had it on your library ages ago you can still play it there in your PC. Sorry to say..if you want support..you have to harass the developer in other ways than here. He is has been AWOL for a long time and wont respond to your questions etc. I find that some devs will update games depending on if it is Linux or Windows...but some like this dev..just abandon them altogether. Sorry mate. It has happened to me ALOT.
