I help game creators turn ideas into playable, polished experiences. For Roblox, I work on combat animations, VFX, Luau scripting, abilities, UI, maps and bug fixes. For Minecraft, I can help with custom builds, maps, server setup and gameplay features. I also create game trailers, thumbnails and short videos that show the best parts of a project. Tell me what you are building, what already works and where you need help. I will review the scope, agree on clear deliverables and keep you updated as the work moves forward.
Other Game Development Services I Offer
FAQ
Can you fix Roblox script errors in an existing game?
Yes. I debug Roblox Luau script errors, broken functions, tools and game mechanics in an existing project. Send the Output error, the affected script and steps to reproduce the issue. I will trace the cause, repair the agreed bug and test it in Roblox Studio before delivery.
Can you fix a Roblox DataStore that is not saving player progress?
Yes. I investigate Roblox DataStore saving and loading errors, including progress that resets after rejoining, missing currency and inventory values. I test the affected save flow and explain the fix. Previously lost data can only be restored when a usable backup or stored record exists.
Can you fix Roblox GUI buttons and mobile UI problems?
Yes. I troubleshoot Roblox GUI buttons, menus, HUDs and mobile controls that do not respond or display correctly. I check the relevant LocalScripts, UI references and client-server events, then test the agreed fix in Roblox Studio on the device sizes included in your order.
Can you fix lag, FPS drops or a slow Roblox game?
Yes. I inspect Roblox game lag, FPS drops, expensive loops, memory use and scripts that slow down gameplay. After finding a reproducible bottleneck, I optimize the agreed area and compare its behavior before and after. Send your game link, affected device and when the slowdown happens.
Can you repair Roblox gamepasses, shops and missing purchase rewards?
Yes. I debug Roblox gamepass benefits, developer product rewards, shop buttons, currency deductions and inventory delivery. I inspect the purchase and reward flow, fix the agreed error and test the result. Tell me what the player buys, what should happen and what happens instead.
Can you fix multiplayer, RemoteEvent or exploit-prone scripts?
Yes. I repair Roblox multiplayer bugs caused by client-server logic, RemoteEvents, RemoteFunctions and missing server checks. I test the affected feature with multiple players where needed. I can improve weak validation within scope, but I cannot promise a game will be exploit-proof.
Can you fix obby checkpoints, respawns and leaderboards?
Yes. I fix Roblox obby checkpoints, stage progression, respawn locations, leaderstats and saved stages. I check whether the problem comes from the checkpoint script, spawn logic or DataStore flow, then test a player leaving and rejoining so the agreed progress works as intended.
Can you audit and fix AI-written or another developer’s Roblox scripts?
Yes. I review existing or AI-written Roblox Luau scripts for conflicts, duplicated logic, broken references and unsafe client-server calls. A small fault fits Basic; one system fits Standard. Larger audits or unfinished games need a custom quote after I review the files.
What do you need to start a Roblox bug fix order?
Send your Roblox game link or place file, Luau scripts, Output errors, a video or screenshot, and steps to reproduce the problem. Include what should happen, what happens now and whether it affects PC, mobile or multiple players. I will confirm the issue and package before you order.
What happens if the bug returns or more issues are found?
If the same agreed Roblox bug returns because of my fix during revision, I will review and correct it. New features, unrelated script errors or problems introduced by later changes require another quote. I will explain any additional issues found before making changes to your game.
