Roblox Free-for-All Fighting Game Development

I'm looking to develop a fun, goofy styled free-for-all fighting game on Roblox. The game should have no specific theme, and will include a variety of key features:

Essential Features:
- Custom combat system with customizable controls
- Round-based gameplay
- Custom walk animations
- Map voting system
- Knockout system
- Teleport back to lobby after losing
- Trading system
- Matchmaking system
- Saved progress system
- Weapon spawning system
- Coin system
- Mystery box system

Ideal candidates should have:
- Strong experience in Roblox game development
- Proficiency in creating custom combat systems
- Knowledge of matchmaking and trading systems
- Ability to implement various game mechanics like teleportation and weapon spawning

Please provide examples of similar work done.
