There’s nothing wrong with taking inspiration from other games or ideas. That’s a normal part of game development. But please don’t accuse me of copying, because the gameplay is different, and once the game is finished, it will be even more distinct. Inspiration doesn’t mean copying.
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.
