Sonic Speed Simulator is a spinoff of the Sonic the Hedgehog series based on the Roblox development platform. It was licensed by Sega to Gamefam Studios, which includes fangame developers such as the creator of Sonic Onset Adventure. After a paid beta period on March 2022, it was released for free on the 16th of April of the same year.
The game starts out on a sandbox-like Hub Level based on Green Hill Zone. At first, players can only move around at a jogging pace but by collecting crystals they can fill out their experience gauge and raise their speed. As they become faster, they'll be able to rack up combos while collecting crystals, move past loopings and leap off ramps to collect bonus items and gain levels more and more efficiently. This goes on until reaching the level Cap, after which players can start over with a higher limit and a potential for comically high and uncontrollable speeds.
This game contains the following tropes:
- Ascended Meme: During the 2022 birthday event, a hidden graffiti on Green Hill reads "Santiago is GONE", referring to the developers doing their best to model a good-looking Japanese-style Classic Sonic so that it doesn't come off as a "Santiago"
. That is a meme that criticizes the look of Classic Sonic in Sonic Generations and Sonic Forces as unfaithful enough to his portrayal in the Mega Drive era that he might as well be considered a different guy. - The Bus Came Back: The game brings back the Shadow Androids, using their updated colored designs from the Sonic IDW comics.
- Boss-Only Level: The Metal Madness event requires players to beat Metal Sonic in a race at Stardust Speedway. Their speed is equalized with Metal Sonic's, though bonuses from a equipped Chao will still apply.
- Bribing Your Way to Victory: Players can exchange Robux, the virtual currency of Roblox, for more advantages.
- Cap: The speed level first caps out at 50, which unlocks the Rebirth function. It will reset the player's level while raising the cap by 25 and adding an experience multiplier.
- Easter Egg: On Green Hill Zone, a golden statue of Sonic can be found within a hidden cave. Various developer messages and stickers of characters like Eggman can also be found at certain corners.
- Hub Level: Green Hill contains gates to all of the other zones in the game that are unlocked by clearing certain conditions.
- Mythology Gag: One of the character skins is of Knuckles wearing the hat from his OVA incarnation. Both Sonic and Tails also have costumes based on plushes sold in the nineties, while Amy has a chef outfit based on a Sonic Channel illustration.
- No Plot? No Problem!: There's no story in the game.
- Play Every Day: The game contains periodic rewards and timed events to draw people in.
- Recycled Soundtrack: All the game's music is taken from previous entries in the series.
- Score Multiplier: The more crystals you collect in a row, the more points they'll be worth. More multipliers are granted by rebirthing and equipping both a Chao and a speed trail.
- Secret Character: Players start out as their default Roblox avatar and must unlock everyone else including Sonic by finding hidden cards or completing certain tasks. They're all just skins with no unique abilities, though.
- Wide-Open Sandbox: Every zone is an open field to run around in, with no enemies or hazards.
