Deep polish pass on Number Go Up — tabs that silently didn't work, milestone particles that only fired for auto-clickers, decimal upgrades that bloated every price label — plus ripping out a Millionaire Mode implementation that had been built against an imaginary spec and rebuilding it against the real spec that was sitting on disk the whole time.
Number Go Up: Fix Everything That Was Quietly Broken
The tabs in the left panel didn't work. Like, at all. There was no CSS rule hiding inactive .tab-content divs, so Upgrades + Store + Settings were all stacked on top of each other and clicking the tab buttons just toggled some classes with no visual effect. Two-line fix, shipped. Then the numeric-milestone particle bursts: the code was if (state.totalNumbers >= m && state.totalNumbers - gained < m), where gained was only the per-frame NPS amount. In early game there are no auto-clickers, so gained === 0, so the < m check is never true. Milestones literally never fired for click-driven progress. Rewrote it as a stateful cursor that walks forward through the threshold array and seeds from totalNumbers on load and prestige. Decimal places was the third quiet bug — formatNum ignored the player's decimal setting in K/M/B/T ranges, then after I fixed it I immediately had to cap decimals at zero for upgrade cost displays because nobody wants to see "1.5000M Numbers" on a buy button.
The Rest of the Polish Pass
While the file was warm:
| Feature | Change |
|---|---|
| Currencies panel | Moved from bottom of left panel to top of center panel |
| Bigger Font upgrade | Deleted; --number-size is now clamp(2.6rem, 6.5vw, 5rem) |
| Fourth Wall Repair Kit | Silence scales level × 30s; maxing it unlocks a permanent narrator-mute toggle in Settings |
| Number Multiplier | Renamed → Click Multiplier with explicit "does NOT affect NPS" copy |
| Critical Click | Description said 5%, code said +2% per level. Description lost the argument |
| Exposure Bucks | Finally have a use: a 500 EB Verified Checkmark cosmetic that does absolutely nothing |
| Save / Load / Delete | Save Now has button feedback, Load button added, Delete uses cancelable confirms |
Millionaire Mode, Take One: Built the Wrong Thing
Spun off a subagent to implement Millionaire Mode for Idle Dread. Wrote the spec myself, off the top of my head: a single "Hollow Validation" bar that drains over time, small Purpose regen bonus, satirical framing, ship it. Agent built it faithfully. User played it. User said: does that actually cover the spec we discussed? sounds like a shell. Because the real spec was already on disk at idle_dread/MILLIONAIRE-MODE-SPEC.md. Written previously. Sitting right next to the file I was editing. I never grepped for it.
Millionaire Mode, Take Two: Built What the Spec Actually Said
Ripped out every trace of the Hollow Validation approach (verified via grep, zero hits) and spawned a fresh agent pointed directly at the real spec. This time: S.millionaireMode parallel state machine, six reskinned meters (Paranoia / Aged Scotch / Legacy / Ennui / Influence / Dopamine — all display-only so the math reuses existing corporate-mode code), five stages from "New Money" through "Recluse", thirteen millionaire upgrades, ten hustles including random-payout angel investing and always-loses-money NFT collecting, a "Stay in The Void / Become Your Own Boss" choice dialog at $500K lifetime earnings, an "Existential Audit" prestige reskin with five snooty titles, and a Mogul theme that auto-applies via body.mm-active. Dev panel got three buttons — Show Choice, Enter MM, +Stage — so you can skip the grind to playtest it.
Lesson Filed
Saved a new feedback memory: always glob for *SPEC* / *PLAN* / *DESIGN* files before writing an agent prompt with an invented spec, especially when the user says "the plan" or "we discussed this." Existed-on-disk-the-whole-time specs are embarrassing in a way that re-runs a whole feature. The fix is a five-second glob. There is no excuse.
What's Next
- The Grindstone has a 712-line pre-existing diff from another session — settings dropdown, chat filters, death/pause overlay with XP penalty, Mage Time Warp buffs. Needs its own review and commit
- Playtest Millionaire Mode end-to-end; expect the first pass of event copy and stage pacing to need tuning
- Millionaire Mode's billionaire tier is already sketched in the spec as "out of scope" — second reskin following the same pattern when the itch strikes
