I'm MuffinHandler. I've built on Roblox for 10 years and founded Playscape, my own games company, in 2022. I own every game here and run them end to end: planning, scripting, UI, analytics and weekly live ops.
Games I own and run
Unedited gameplay from my games: the RNG garage reveal in Car RNG, rolls, combat and upgrades in Slime Simulator, and building in Waterpark Tycoon.
Each of these is mine: I designed it, built it and ran it after launch. Numbers are from Roblox's public API.
My biggest game. A two-player co-op tycoon where friends build one base together. It carried Tycoon Playground to 5.5M members, and the 2-player format carried into the tycoons that followed.
Build your own waterpark: pools, slides and decks unlock stage by stage, and guests pay to swim. GamingWithKev played it on his channel; that video alone has over 400K views.
Roll for real-world-inspired cars from Common to Exotic. Every roll plays out in a garage: the shutter lifts, the car is lit, and the rarity lands with a burst sized to the odds.
Roll slimes, fight through zones, rebirth for luck. It's one of three slime games I launched in 2026 on a shared codebase (with Roll a Slime and Slime Empire Tycoon), each tuned as its own product.
A selection of the 44 live games at Playscape. Lifetime visits from Roblox's public API; updated 30 September 2026.
I run updates the way a producer should: small scope, a fixed date, a test pass, and a look at the numbers after it ships.
Pick the one goal for the update, cut everything that doesn't serve it, split the rest into tasks.
Luau systems, UI and art in parallel, with AI agents wired into Studio and Blender doing the heavy lifting.
A weekly cadence behind one release switch, so a wave goes live with one command and rolls back just as fast.
Funnels, economy tracking and live configs show where players drop off. The next update starts there.
I take updates from plan to release. I scope the work, split it into tasks, set the release schedule, test it and check the numbers after launch.
Weekly update waves with new zones, pets and rebirth caps, timed events, daily quests and rewards, balance passes and prices tuned against top games.
Roblox analytics end to end: economy tracking for every currency, onboarding and progression funnels, live configs for A/B tests.
Tycoons, RNG rolls, pets, player data and monetization, plus the performance work that keeps a full server smooth.
Claude Code and Codex connected directly to Roblox Studio and Blender. They script, test, profile and produce assets.
HUDs and panels built on one structure that works with touch, mouse and keyboard, and gamepad.
Dev product and game pass icon sets, sprite sheets and item art that sell the purchase at thumbnail size.
Happy to do a test task. The fastest way to reach me is email or Roblox.
