The hardest part of a Roblox game is not the building, it is the scripting that makes it fun and keeps players coming back. Pick a loop that is simple to grasp and satisfying to repeat, then layer progression on top.
Each idea below is a real, scriptable game. Assemble the world in Roblox Studio, and describe the mechanics on Devellix to get the Luau scripts and a Rojo project you can sync in.
