Feedback on my game

I have made a game called Physics test and i want to add more to it so the players play more

Here is the game : Physics Test - Roblox
People dont play much on my game I also need help with advertising what style should I go for?

i think it is due to the fact you have to serverhop for a new fresh server and that the map seems awkward in appearance compared to the default parts in anesthetic

also there’s not much interaction in colliding a interesting cause in physics such as if you were to hit a rapid velocity ball to a ball that is also going closer but at a smaller pace while they are both tied so adding refresh buttons (client-sided to prevent lag spam with a cooldown) can be important

I will make it so the items respawn every 1 minute thanks the feedback
