PM polish update: just pushed an updated build to the browser demo!

- Clearer rule guidance on title pills: added "Hot ends the room" alongside "Silent unless Seen" / "Seen · Loud".

- Room 1 coach now explicitly notes that firing while Seen triggers Hot and restarts the room.

- Coral alarm feedback pulse when Hot.

Playable demo (first 3 rooms): https://shellsharker.itch.io/hushline

Still looking for any first-impression feedback on whether the stealth rules feel intuitive immediately.

Hi everyone! I just released an updated HTML5 browser demo for Hushline: https://shellsharker.itch.io/hushline

Hushline is a short stealth third-person shooter (top-ish camera, 10 rooms total; demo covers the first 3 rooms playable directly in browser).

Core mechanic / rule:

Your gunshots are completely silent UNLESS an enemy line of sight is actively seeing you when you fire — then your shot is loud and the alarm meter climbs (triggering hunting guards).

What I'm looking for specific feedback on:

1. Is the core rule clear within the first 60 seconds of playing room 1?

2. When the alarm hits "Hot", does the coral rising-edge toast and blinking indicator communicate what went wrong clearly?

3. How do the controls (WASD move, mouse aim + click shoot, Shift sneak) feel in the browser?

Playable demo link: https://shellsharker.itch.io/hushline

Any feedback on pacing, visual clarity, or controls is hugely appreciated!

New free HTML5 demo — Hushline. Silent shots unless you're seen; alarms in 10 rooms. Demo is rooms 1–3 in the browser.

https://shellsharker.itch.io/hushline

Hushline is a short stealth third-person HTML5 takedown shooter: top-ish camera, ten rooms, silent rounds — until someone can see you. Then the alarm climbs.

Sneak the cones. Drop the floor. Bodies, cameras, and bare metal raise the same meter. Clear every guard and the door unlocks. Fail only restarts the room.

Hi! I’m looking for a few players to try Afterimage, a short thinky HTML5 puzzle cabinet: commit a path, then solve with a looping magenta ghost.

Play the free in-browser demo: https://shellsharker.itch.io/afterimage

The full game is $4.99 on itch; the five-game Shellsharker Puzzle Cabinet bundle is here: /s/200787/shellsharker-puzzle-cabinet

I’d especially love feedback on whether the loop/ghost rule is clear in the first few levels, and where the difficulty starts to feel fair or opaque. Thanks for playing!

Signal Fold is a short thinky HTML5 cabinet: cycle fold mirrors on a dark grid, then Fire a pulse that must bounce into every receptor without dying on dead tiles.

Not a maze. Not a light-up. Aim the beam with limited folds — teal receptors lock when the chord hits; dead zones eat the shot.

Afterimage is a short thinky HTML5 cabinet: you walk a path, hit commit, and a magenta afterimage replays that exact route forever while the living player finds a second way out.

Time does not reverse. It stacks. Park ghosts on switches, throw them into lasers, open doors you cannot hold yourself. Later levels want a chorus of afterimages all looping at once.
