The only way I could see a game like this getting players is by appealing to really young kids. Having stuff like those really trendy-ish thumbnails on the explore section of Roblox.
Sadly, I find it really difficult for your game to grow as it doesn’t copy off a current roblox trend, nor it is an original concept.
Uploading it to a different game wont do much, sorry.
There’s lots of new-ish Speed Run games with many players, and some of them got thousands of players last year! I updated the original post with an image of them
I believe the Visits count has nothing to do with your appeal to the target audience, because there are dead games that were popular years ago (Survive the Disasters, Find the Domos, etc.). The best you could try is to make it look promising to new players, and push frequent updates to keep the retention going.
