Roblox Game Development
Budget: €1,500 – €2,000 EUR
Hi! I'm looking for an experienced Roblox developer to build a game called Keep It Floating.
The concept is inspired by the satisfying and challenging gameplay of games like Keep It Up!, but redesigned specifically for Roblox with progression, replayability, and monetization in mind.
Core Gameplay
The main objective is simple:
The player must keep a balloon floating in the air while completing a first-person parkour course.
The balloon should have realistic but satisfying physics. The player constantly interacts with it by hitting it upwards to prevent it from touching the ground.
If the balloon touches the ground, the run immediately ends and the player has to restart from the beginning (or from checkpoints if we decide to include them).
The controls are the most important part of the game. They need to feel extremely responsive, polished, and satisfying. I want the balloon movement to be fun, predictable, and rewarding to master.
The game should be played entirely in first-person, with the player's Roblox hand visible on screen at all times to make interactions feel immersive.
The overall gameplay loop should be very easy to understand but difficult to master.
A complete run through all levels should take under 45 minutes for an average player.
Levels
The game should contain 10 handcrafted levels.
Difficulty progression:
Levels 1-3 → Easy
Levels 4-7 → Medium
Levels 8-10 → Hard
Each level should introduce new mechanics instead of simply increasing obstacle density.
Examples include:
Moving platforms
Rotating obstacles
Fans that push the balloon
Narrow parkour sections
Elevators
Timed doors
Precision jumps
Wind zones
Buttons that activate new paths
Dynamic obstacles
Falling platforms
Every level should feel unique while keeping the same core mechanic.
Progression System
I don't want this to feel like a one-time experience.
I'd like a complete progression system including:
Player XP
Player Levels
Coins/Currency
Statistics
Time Played
Balloons Saved
Successful Runs
Wins
Personal Best Times
Everything should be saved using DataStore.
Missions
I would like a mission system that encourages players to return every day.
Examples:
Complete 3 runs.
Reach Level 5.
Hit the balloon 500 times.
Finish a level without failing.
Complete a run in under 10 minutes.
Play for 20 minutes.
Collect hidden collectibles.
Complete a level without using a boost.
The mission system should support:
Daily Missions
Weekly Missions
Achievement-style permanent missions
Players should receive XP, coins, titles, or cosmetics as rewards.
Boost System
I'd like a boost system that players can unlock or purchase.
Examples:
Double XP
Double Coins
Faster Movement
Bigger Hitbox for the balloon
Slower Balloon Fall Speed
Extra Time
Temporary Shield
Lucky Boost
Checkpoint Token
Boosts should feel useful without making the game completely pay-to-win.
Monetization
The game should support:
Gamepasses
Developer Products
Future cosmetic content
Possible purchases:
Balloon skins
Hand skins
Trails
Particle effects
Goal animations
Win animations
Titles
Name Tags
Emotes
Boosts
VIP
The monetization should focus on cosmetics and convenience rather than unfair advantages.
UI
I'd like a polished and modern interface.
Including:
Main Menu
Level Selection
Shop
Inventory
Missions
Boosts
Leaderboards
Settings
Daily Rewards
Notifications
XP Bar
Coins Counter
Everything should feel smooth and responsive.
Visual & Audio Feedback
This is one of the most important parts of the game.
Every interaction should feel satisfying.
Examples:
Balloon hit effects
Particles
Camera shake
Glow effects
Combo effects
Success sounds
Failure sounds
UI animations
Reward popups
The game should constantly reward the player with visual and audio feedback.
Leaderboards
I'd like global leaderboards for:
Fastest completion time
Highest Level
Most Wins
Total XP
Most Balloon Hits
Performance
The game must be optimized for:
PC
Mobile
Console (if possible)
The code should be clean, modular, and easy to maintain for future updates.
Future Updates
The project should be built so new content can easily be added later.
For example:
More levels
New worlds
New balloons
Seasonal events
Limited cosmetics
New missions
Additional boosts
Challenge modes
Hardcore mode
Time Trial mode
What I'm Looking For
I'm looking for someone who has experience building polished Roblox experiences, not just scripting mechanics.

My priority is creating a game with excellent gameplay feel, smooth physics, satisfying feedback, and a strong progression system that keeps players coming back.
