Hi!
Please watch this demonstration of my custom ProximityPrompt GUI, and let me know if it needs any improvement with a reply or not then just heart (i dont want feedback on the other parts of the game, just the prompt design and sound please).
Thanks in advance 
Is this a custom system, or is this just a retexture of the default roblox one?
Retexture - I used Proximity Prompt Customizer to edit the original roblox prompt, and also changed some lines in the script to make it tween smoothly.
I used ProximityPromptService.PromptTriggered in a local script to play a sound in the client each time a proximity prompt is used.
