Make your own game

Brainrot Run was built by dsfdfdhjdfjdfh with the Cinevva game creator: describe the game you want in chat, watch it get built, and play it in your browser minutes later.

Remix Brainrot Run opens the real game in the creator and forks its actual files, chat and design doc, so you start from the code rather than from a description.

Read the build brief for Brainrot Run

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a playable 3D third-person arcade collection-and-return game titled “Brainrot Run.” The player controls a simple chunky white low-poly capsule character in a bright, stylized low-poly outdoor world. Use a fixed-length linear map running along the X axis: a wide green grass ground plane, a tan central path about 12 units wide extending roughly 240 units into the wilderness, and a blue safe Base zone at the near/left end, with a light-blue wall/beacon structure marking the rear of the base. The camera should follow behind and slightly above the player, looking forward down the path; use a bright sky-blue background, soft fog, shadows, and readable arcade colors.

The core loop is: begin near the Base, run out along the path into the wilderness, collect floating colored Brainrot relics, return to the Base, and hold Space to deposit the carried items onto available Income Pads. Carried inventory starts at 3 items. The HUD must clearly show Cash, Carrying (for example 3/3), Income/sec, and Speed. Deposited items remain on pads and produce passive cash continuously according to their tier value. Start with two Income Pads in the Base, arranged as two rows/columns near the beginning of the map; pads are dark/off when empty and become glowing orange/color-coded active pads when occupied. Include bottom upgrade buttons for Buy Speed, Buy Capacity, and Buy Pad. Speed costs

5 initially and increases by

0 per purchase; each speed upgrade raises normal movement speed by 12%. Capacity costs $40 initially and increases by $30 per purchase, adding one inventory slot. A Pad costs $75 initially and increases by $50 per new pad, adding another income pad. Disable or show a clear “Not enough cash” toast when the player cannot afford an upgrade. Populate the wilderness with about 34 floating, slowly bobbing and rotating faceted relics, each with a glowing ring on the ground. Spawn them mainly from X=14 through the far end, across the central path and nearby side lanes. Relic tiers should become more likely farther from Base: Common yellow “Noobini Cakenini,” value 1; Rare green “Tigrilini Watermelini,” value 4; Legendary purple “Blue Smurf Cat,” value 10; and Divine red “Sigma Boy,” value 22. Use yellow/green/purple/red geometry and rings to communicate tier. Picking up within close range removes the relic, adds its tier to inventory if capacity is not full, plays a short pickup sound, and displays a toast with the relic name. When fewer than 12 relics remain, replenish the field. Add environmental decoration away from the main route: scattered gray low-poly rocks and simple stylized trees made from brown trunks and green cone crowns. Add four dark rectangular trenches at approximately X=48, 96, 144, and 192, alternating on opposite sides of the path. When the player is close to a trench and holds Space, lower/hide the character in it and mark them as hidden; while hidden, the character is safe from a passing wave. Release Space to leave the trench. The player can move with WASD or arrow keys, sprint with Shift at a 1.55x multiplier, and move freely within bounded X/Z limits. Space also deposits inventory while in the Base. Keep the on-screen hint text: “WASD move • Shift sprint • Space deposit / trench,” changing it while hiding to “Hidden in trench — wait for the wave to pass.” Implement the Tsunami system as a repeating timed hazard. Before a wave, the center HUD should show “Next Tsunami: [countdown]s,” with the countdown initially about 45 seconds and subsequent intervals randomized around 42–54 seconds. When the timer reaches zero, spawn a huge translucent vertical wall crossing the full width of the map, about 10 units thick, 18 units tall, and 52 units wide, starting beyond the far end and moving toward Base along the X axis. Randomly choose its type and color/speed: blue wave, about 45% chance and speed 16; red wave, about 35% chance and speed 24; or pale lightning wave, about 20% chance and speed 33. Display a warning toast such as “BLUE TSUNAMI INCOMING,” and while active replace the countdown with a label like “BLUE wave — [distance]m out.” If the wave passes the player and the player is neither inside Base (X<2) nor hidden in a trench, treat it as a hit: clear all carried inventory, teleport the player back near Base at approximately X=-8, Z=0, and show “Wave got you — dropped your haul.” The wave should continue past Base, then disappear and start the next countdown. Base is safe from waves, but deposits require being in Base and pressing Space. Use a clean, strongly readable HUD in dark semi-transparent navy rounded panels over the top of the 3D view. At the top-left show the four stat rows; beneath it show the tsunami countdown/status and control hint in a centered panel; along the lower portion show blue rounded upgrade buttons with white text. Include brief toast notifications for pickups, deposits, incoming waves, failed runs, and insufficient cash. Use simple pleasant synthesized arcade tones for pickup, deposit, upgrades, wave warning, and being hit if audio is available. The game has no hard ending: the objective is to survive repeated waves, build passive income, collect increasingly valuable distant relics, and buy upgrades into a more efficient hauling loop. Do not add unrelated enemies, weapons, combat, or extra win conditions.
