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: https://itch.io/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!

Parity Shift is a short thinky HTML5 cabinet: stamp a glowing cross on a dark parity field. Every stamp flips the center tile and its neighbors. Match the mint ghost pattern before the stamp budget dies.

Not a maze. Not a beam. Lights-out with a budget — order does not matter, parity does.

- Free in-browser demo (first 8 levels)

- Full game 24 levels · $4.99

Gridlock Pulse is a short thinky HTML5 traffic-cabinet puzzle: toggle H/V lamps, then STEP the pulse so cars clear every green without crashing.

Stage the lights, commit the tick. Wrong phase and something gets wrecked. Right phase and the intersection sings.

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.

Shellsharker also has paid cabinet puzzles if you want more.

Hi! I’m the developer behind Shellsharker, and I’ve just released ORBIT DOCK, a short, thinky browser puzzle about placing gravity wells to guide a drifting probe through near-black space.

The free demo runs in your browser: https://shellsharker.itch.io/orbit-dock

Place a well, launch, and read how the probe curves. The demo has 8 levels; the full game has 24 handcrafted levels with soft catches, reverse docks, and three-body pulls.
