HAMSTER FRIENDSHIP – MOBILE CONTROLS & CLOUD SAVE IMPROVEMENT

The joystick change works. I found no high or medium defects and one low one: the "Sword" label is wider than its weapon button on small phones. Nothing in the repository was changed; the finding is in .imd-findings.json.

The brief I was given is cut off. It stops at "No buttons may be clipped, pushed outside". The title also promises a cloud-save improvement, but none of that text reached me, so I could not judge it. I have listed it as "needs the requester".

Requirements

1. "Replace the current left-side touch buttons with a virtual joystick": met. #joystick and #joystick-knob in src/index.html; the old left-half drag surface is gone.
2. "forward and backward movement only": met. aimStick in src/game.js reads only the finger's horizontal position, and the up/down value is always 0. In a real touch drag in Chromium, moving the finger up and right kept Chang's height at 146 the whole time.
3. "Do not allow left/right movement or diagonal movement": met, as read for a side-scroller. Here forward and back are right and left on screen, and there is no up/down or diagonal steering (the old 8-way drag code is deleted).
4. "smooth, responsive and continuous": met. Input eases toward the finger each frame and speed blends in rather than snapping.
5. "analog input or a normalized forward/backward value": met. stickValue returns a value from -1 to 1. The builder's own validator checks that a half push walks slower than a full one.
6. "small dead zone": met. The dead zone is 16% of the knob's travel. A 3px push left Chang at x=96.
7. "movement must stop smoothly" on release: met. Release uses the same slow-down as letting go of a key; x went 206 → 209 → 209 over about 80ms.
8. "fixed … near the bottom-left corner": met. The joystick sits 16px from the left and bottom edges at 390x844, 844x390 and 1024x768.
9. "does not interfere with gameplay or other touch controls": met. No overlaps at any size I measured. The builder's validator covers using Jump and Attack with other fingers while walking.
10. "All mobile touch controls must remain completely inside the visible game frame": met. I measured six sizes (390x844, 320x568, 844x390, 568x320, 667x375, 1024x768), with and without the PICK UP and Read prompts. Every control was inside the screen and the touch area, nothing was hidden under another element, and nothing overlapped.
11. "No buttons may be clipped": met for the buttons' outlines, with one low finding. The "Sword" label sticks out of its button by 2–3px at 320x568 and 568x320.
12. Cloud save improvement (title only, text cut off): needs the requester. The live Supabase setup and a redeploy of the edge function (supabase/functions/_shared/engine.js changed in this commit) are theirs to do. The title screen says so plainly: "Cloud saves unavailable".

Finding

• low · bug: the "Sword" (and at 320, "Bomb") label is wider than its weapon button. Source: src/styles.css:488. The fix is --slot-w: max(50px, …); I measured that the slot row still clears the joystick at both sizes.

The idea

A pixel-art side-scroller in autumn tones, with plain, dark-backed touch controls framing the scene and the gold Attack button as the one accent.

How I checked

• Design probe: ran it with the Playwright already installed outside the repository; all 16 checks passed.
• My own measurements: a script in test/scratch/review/ (scratch space, removed before submission) served dist/. It started a run, measured every control, forced both prompts visible, and sent
