Why do games like these go abandoned while unpolished games like wildlife is still alive?
Developer said that they stopped because of Israel War, when it broke out. Maybe they are Israeli, or just Jewish, and realized how far they went off the path, and wanted to cut all ties to the title. I say that in theory, as I talked to them over on Itch at one point, and they had said they've been wanting to make a game like this for like 5+ years, so what I'm thinking is that he has a friend/family who is Israeli / Jewish, they found out about the game, and guilt-tripped him until he abandoned it.
As for Wild Life... its because people want gallery-style porn more than they want the gameplay. Otherwise, the money would have dried up fairly fast after they gave up on making a game.
