SCPM: Found an entry for Keen Dreams (again, nothing visible yet):
https://api.gog.com/products?ids=2090792369 Hopefully that won't be the only Captain Keen game here.
It will likely be the only one. "Harddisk Publishing" has shown up as a company in the catalog. The
Mobygames page mentions:
Unlike the other Keen games this game was not published by Apogee but by Softdisk. The id developers were all former Softdisk employees and when they formed id, the group still had the obligation to produce a couple of games for Softdisk.
Removal from Steam
The game was removed from Steam on July 19, 2017, after Valve severed their relationship with the publisher due to multiple complaints about their behavior - and changing their company name into an insult against Gabe Newell, one of Valve's founders.
No idea about the rename, but the complaints about the behavior
could be related to this.
