I found the developer. It looks like it's Zerat Games? But the game isn't for sale on their website.
Still no link to the game
Viewing post in Where can I buy No Mercy?
This is actually very interesting. The blue box was a purchase box last night. Looks like he's pulled it again from his own site.
EDIT: I found the original link. It looks like he was hosting the sale of the game through a site dedicated to NSFW art and pulled it. It also looks like his previous twitter account has been disabled so he may be dodging the spotlight with all of the traction that this is getting.
