It’s not a rip-off. The game works differently and plays differently. If you think every game with some similarities is a rip-off, then you’d barely be able to play anything.
Honestly, you just gave the game the best marketing it could’ve asked for. Anyone who actually plays it will see it’s different. Your blaming and crying didn’t hurt it it just made more people curious. If you had stayed quiet, nobody might have cared. Instead, you turned it into a bigger deal all by yourself.
