This college assignment calls for a compact yet polished circuit-style racing game built entirely in Roblox Studio. The track should accommodate car-only racing and include a reliable lap-based time-trial system so I can demonstrate leaderboard logic and basic analytics during my presentation. Key notes: • Cars are the sole vehicle type; no bikes or karts are necessary. • A clean, looping circuit with start/finish detection, checkpoint scripting, and lap counting must be in place. • Time-trial functionality is essential—automatic timer start, per-lap splits, and a simple top-five leaderboard stored with DataStore. If you already have frameworks for multiplayer or cosmetic customization, feel free to structure the code so those could be added later, but they are not mandatory for this delivery. I mainly need solid car physics, responsive controls, concise Lua scripts with comments, and UI elements that look presentable for a classroom demo. Please hand over the .rbxl or .rbxlx file, all associated scripts, and a short read-me explaining where each major component lives in the workspace so I can speak to it confidently.
