Core Crates

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.

Recreate a playable sci-fi reactor management/incremental game titled “Core Crates.” Use a dark blue reactor chamber as the full-screen 3D backdrop, viewed from a slightly elevated, front-facing perspective with a slow gentle camera orbit. In the center, build a cylindrical metallic reactor housing/platform containing a bright emissive spherical core, three intersecting/angled glowing metal torus rings, six outer support struts, four vertical control rods around the core, and small glowing particles orbiting it. The core should pulse continuously and shift from cool cyan/blue when healthy toward orange/red as control-rod integrity falls; the rods should lift and wobble more as they become damaged. Use dark navy surroundings, fog, a large dark circular floor/base, blue metallic materials, emissive lighting, soft glow, and a polished futuristic 3D style. If 3D rendering is unavailable, provide a centered CSS fallback with the same glowing sphere, rings, and four rods.

The game is a resource loop: the reactor passively generates energy over time while the rod array slowly wears down. Start with 40 energy, 88/100 rod integrity, 1.2 base output/sec, 22 repair power, 6% crit chance, no backups, and wear 1.05. Effective output is reduced by rod health: efficiency is 35% plus the rod-integrity percentage contribution, capped at 100%; while shutdown is active output is OFFLINE. The player must manage energy and rod health, buy crates, and install the parts they obtain. There is no character avatar or movement; all interaction is through the management HUD.

Create a glassy, translucent, rounded HUD over the scene with a responsive scrollable layout. On desktop use a top statistics bar and three columns/panels: Inventory on the left, Reactor Status in the center, and Crate Market on the right. On narrower/mobile screens stack the panels vertically, use a two-column stat bar, and make action/install buttons touch-friendly. The top bar must show Energy; Control Rods as current/max; Output / sec; Repair / Cost; and Crit + Backups. Reactor Status must show explanatory status text, a colored horizontal control-rod integrity bar, an “Adjust Rods” button, a “Repair Rods” button, and a Recent events log.

“Adjust Rods” gives an immediate energy burst of 7 plus any manual bonus, with a 5-energy critical bonus if a random roll succeeds against crit chance, but damages integrity by 8 plus wear*2.25. Show a critical event when it occurs. Disable this action during shutdown. “Repair Rods” costs energy equal to max(3, round(12 - repair discount)), restores repair power integrity (and 8 extra during shutdown), and cannot be used when full except during shutdown. Show toast notifications for insufficient energy, already-full rods, shutdown restrictions, repairs, crate purchases, and installations.

When integrity reaches zero, trigger a rod failure. If backups are available, consume one, restore integrity to at least 42% of max or 18, and enter a 1.8-second reboot/shutdown period. Otherwise remove 45 energy (not below zero), restore integrity to at least 22% of max or 12, enter a 4.2-second shutdown, increment a failure count, and report that output is offline until repairs catch up. During shutdown, passive generation and wear stop; repair is stronger by 8. The status text should show the reboot countdown and explain that shutdown repairs are stronger.

The Crate Market must offer three purchase buttons: Scrap Crate for 30 energy, Prototype Crate for 95 energy, and Singularity Crate for 240 energy. Buying a crate consumes energy and randomly adds exactly one part to the bag using weighted rarity tables. Scrap is mostly common with a chance of uncommon parts; Prototype favors uncommon/rare parts and can produce a backup fuse or fusion catalyst; Singularity contains rare through legendary technology. Do not apply a part immediately: crates always place it in the bag first.

Inventory must explicitly distinguish “In bag” and “Installed” totals. For every part owned or installed, show its colored rarity, name, description, bag count, installed count, and an Install button disabled when none remain in the bag. Include these exact upgrade parts and effects: Graphite Rod (common, +0.45 output/sec); Bearing Kit (common, +4.5 repair strength); Copper Coil (common, +4% crit chance); Rod Sleeve (uncommon, +14 max integrity and current integrity, -0.08 wear); Maintenance Drone (uncommon, +7 repair strength, -1 repair cost); Overclocker (rare, +1.1 output/sec and +0.35 wear); Quantum Lens (rare, +10% crit chance and +0.35 manual energy); Backup Fuse (epic, +1 backup and +16 max/current integrity); Fusion Catalyst (epic, +1.9 output/sec and +8 repair strength); Singularity Cell (legendary, +3 output/sec, +15% crit chance, and +1 backup). Installing consumes one bag copy, increments installed count, and immediately applies the effect. Use rarity colors approximately gray-blue common, green uncommon, bright blue rare, purple epic, and gold legendary.

Keep a six-entry recent-event history for crate drops and reactor incidents, with event colors based on rarity. Include an initially empty inventory message explaining that parts go into the bag before installation, and an initially empty log message stating that there have been no crate drops or reactor incidents. Use frosted dark navy panels, pale blue/white text, muted blue secondary text, cyan action styling, green repair styling, and subtle hover/press feedback. Include a small transient bottom toast for actions and failures. The presentation should clearly communicate that the goal is to let energy accumulate, use rod adjustments for bursts, repair before failure, buy crates, selectively install upgrades, and keep the reactor online while scaling output.
