Come on, the game is done on the PC, he only needs to add the Steamworks features. He told me months ago he was doing so, and the game would be out soon.
But, instead of doing so, he instead worked on releasing the game for platforms like the Wii, and Wii U (seriously, how many people are still using these consoles, and did not purchase any platform where the game is already available, like the Switch?), instead of releasing the game on Steam.
It really seems he isn't really all that interested in people buying his game on Steam. He knows plenty of people are waiting for it, and waited a year to get the game on Steam (he acknowledged so, since he receives several emails about the Steam release all the time), but instead of releasing the game as soon as possible, he instead works on porting the game to "dead" platforms.
