Optimum Resource Inc. (the developers) seem to have gone out-of-business, but I am not sure if the rights have been sold to another company, or if not, if they still own the rights to said games, so I can't be sure if it classifies as legal abandonware in the US, which is where their headquarters were located. And at the same time, because they're out of business, there's no way to buy the games.
I searched on Ebay and Craigslist but I have not managed to find anything. I found a reddit post on r/tipofmyjoystick where the author said he found the game on Kelvin's website, but that has not been archived in the Wayback Machine, and now it gives an error saying that the page was not found. There's also a WorldCat link there, but it's not of much use here.
Does anybody know what happened to them, and where to get them?
