Roblox Multi-Mode Survival Game

I want to launch a single Roblox experience that merges five popular ideas into one cohesive, replay-friendly package:

• “Steal a Brainrot” – a light-hearted stealth sequence where players sneak into guarded zones to capture a Brainrot pet.
• “Escape Tsunamis for Brainrots” – a frantic wave-dodging obstacle run.
• “Escape Lava for Brainrots” – vertical parkour as rising lava forces quick decisions.
• “Grow a Garden” – a calm, timer-based farming loop that produces buffs or cosmetic items.
• “Adopt Me”-style pet raising – players care for, trade, and level up their Brainrots.

Survival is the core theme, so each activity should feel like a challenge to stay alive or keep a pet safe. Progression is level-based; clearing any activity or caring for a pet earns XP that unlocks new zones, cosmetic rewards, and harder difficulties.

What I need from you
1. Design and script every mode in Roblox Studio using clean, modular Lua.
2. Create or source low-poly assets, animations, simple UI, and ambient audio that fit a playful survival vibe.
3. Implement data persistence with DataStore so pets, garden crops, and player XP carry over between sessions.
4. Build a central lobby that lets players queue into each activity, track levels, and trade pets.
5. Optimise for mobile and desktop, test with at least 20 concurrent users, and fix any game-breaking bugs.

Acceptance criteria
• All five modes load from the lobby without errors and award XP on completion.
• Pets, crops, and cosmetic items save and reload correctly.
• A first-time player can reach Level 10 in roughly 30 minutes of mixed play.
• Frame rate holds 60 FPS on a mid-range phone in every scene.

We can discuss milestones and pricing once you outline your approach and estimated timeline. Please share links to previous Roblox projects that show complex gameplay, data persistence, or pet systems so I can gauge fit.
