Steal a brainrot copyright me?

im making a game like steal a brainrot

, i only got the idea from them every thing else by me?

any ways i made it here is the game :

I mean, should be fine more or less, other people steal each others ideas, its not new.

Though im worried about preformance, if people already play and existing game, why would they play yours/a copy, yknow?

dont worry i have smth very special in it, i just scary from copy right

I mean if you say so, but copyright shouldn’t be an issue if you didn’t copy anything from their game.
