Help with copyright

I’m currently remaking the roblox game adventure story (which has been abandon for 4 years now) and the developer seems to want nothing to do with the game now as they’ve ignored my messages asking for permission to copy the game and blacklisted the words “adventure story” from their discord.

I decided to copy the game to the 100 percent using my own scripting knowledge rather than using exploits to copy the game (which is what I’m scared roblox will think)

Can my game get taken down by a random mod who sees the game? (its unlikely the dev of adventure story ask for it to be taken down I feel). I have also used this copy of the map from the toolbox which I’m 100 percent sure was taken using exploits am I still aloud to use that before making the game public or will I need to remake it my self and if so could I just rip the textures and images from the map to make it more accurate, could I just copy the map to the 100 percent too and is me replacing the blocks going to prevent any type of exploit detection as I’ve seen people get banned for using toolbox items that were stolen using exploits??

(Made a similar topic like this before but it wasn’t so helpful basically all I learned was the owner probs cant care less)

This could be moderated.
Even if the game has been abandoned, copyrights still exists.
If you don’t have any authorization from the creator, you may not use the same name or same story.
However, if you change the game name and modify the storyline of itself, you might not having copyrights problems.
