Hey fellow game developers!

For OBOL: The Cursed Coin Pusher, we took on an unusual engineering challenge: shipping the exact same 1890s occult coin-pusher roguelike with 1:1 deterministic physics, camera, shader, and procedural audio parity across three engines: Three.js WebGL 2, Godot 4.7.2 (Vulkan Forward+), and Unity 6 (URP + PhysX).

1. Solving Multi-Layer Coin Stacking at 240Hz (dt = 1/240s)

At standard 60Hz, a reciprocating hydraulic shelf shoving 85+ overlapping cylinder tokens against a back stopper wall causes severe Baumgarte popcorning and tunneling. By stepping all three physics engines at a fixed 240Hz substep (Time.fixedDeltaTime = 1f/240f in Unity 6; physics_ticks_per_second = 240 in Godot 4.7; 4x substep impulse solver in WebGL 2) with 3-layer overburden friction damping, coins hang up to 55% over the front brass lip before cascading.

2. 25-Category Zero-Sample Circular Plate Modal Synthesizer

Instead of bundling megabytes of static .wav files that comb-filter during 40-coin avalanches, we synthesize all 25 metallic & mechanical foley categories in real time using 4-mode Chladni circular plate eigenfrequencies (f0 * [1.00, 2.14, 3.41, 4.92]) routed through an iron-booth convolution impulse response.

Hey Itch community!

We just launched OBOL: The Cursed Coin Pusher (v1.0)-a dark 1890s mechanical arcade debt-rigging roguelike that asks: What if Balatro and Buckshot Roulette lived inside a 240Hz rigid-body coin pusher where your fingers are the collateral?

Hey fellow devs!

While building OBOL: The Cursed Coin Pusher (an 1890s occult debt-rigging roguelike where you rig a mechanical coin pusher to pay off an animatronic Collector before a 3D Finger Guillotine takes your digits), we had to solve two gnarly technical problems:

1. How do you make stacked coins hang 45% off a brass lip without jittering or sliding like hockey pucks?
2. How do you play 70 metallic coin collisions per second during a cascade without .wav sample machine-gunning?

Here is a breakdown of how we solved both across our WebGL 2, Godot 4.7.2, and Unity 6 builds!

1. Why Coin Pushers Need a 240Hz Sub-Stepped Solver (dt = 1/240s)

• Ratcheted Shelf-to-Pusher Friction: Coins on the upper shelf inherit 100% of the pusher bar's forward stroke while asymmetric friction (mu_pusher = 0.52 vs mu_shelf = 0.28) compresses the bed on the backstroke.
• Overhang Torque Counter-Balance (Z = +3.35): Downward normal weight from overlapping rear coins counteracts tipping torque at the lip-allowing multi-coin overhang bridges to teeter on the edge.
• Live On-Board Mythic Fusions: When 3 matching tokens cluster within d < 1.15 on the moving shelf for 0.65s, lightning merges them live into a giant 1.45x-radius Mythic Medallion.

2. Zero-Sample Euler-Bernoulli Brass Plate Synthesis

Instead of shipping .wav files, OBOL uses 0 external audio samples. All 25 sound categories are generated procedurally using inharmonic circular plate modes ([1.00, 2.08, 3.41, 4.96, 6.72]) scaled by coin mass and collision velocity from the 240Hz solver.

Happy to answer any questions about the 240Hz constraint solver, WebAudio/PCM modal synthesis, or how we kept 100% mechanical parity across WebGL 2, Godot 4.7, and Unity 6!

Thanks for giving it a try! Really appreciate the feedback. You're right, the demo could be a bit longer to give players a better feel for the game. We'll definitely take that on board!

Hi itch community — I’m Ahmed, the solo developer behind Cinderline Studio / ANKH ENTERPRISE LTD.

One twist changes four tiles. Read the target, then plan the turn.

Play the first five puzzles in the browser, or download the entire 60-level game free ($0 or optional donation). Daily, Blitz and the level editor are all included. Click, tap or use the keyboard; Undo lets you experiment. Sample progress stays separate from the full game.

TileSpin Retro is a compact logic puzzle game with a 16-bit arcade presentation. Each pivot rotates the four tiles around it. Compare with the target and use Undo to test another route.

Actual shipped-game Level 8 solve, beyond the free five-level sample, captured 28 October 2026 at normal speed. Level access was staged for capture; the puzzle and its rules are unchanged.

Download the 16-second gameplay preview — VIDEO ONLY. The silent MP4 shows a continuous Level 11 solve at normal 1× speed. Level access was staged; the bundled solver supplied the route and actual UI clicks executed it. It is a video, not a playable demo.

The complete collection includes 60 campaign levels across six worlds: 3×3 starts, locks, linked pivots, one-way rotations and 5×5 patterns. Daily puzzles, a three-minute Blitz mode and a custom puzzle editor with shareable codes give you different ways to approach the rules.

TileSpin Retro is free for Windows, Linux and offline browser download. All editions include 60 levels, Daily, Blitz and the editor—no ads, subscription or extra level payments. Only the five-level demo is embedded on itch; the full browser edition is an offline download. Download: https://cinderline-studio.itch.io/tilespin-retro

Disclosure: AI assistance was used for presentation code, pixel-symbol construction and listing text. The licensed Silkscreen font is credited on the game page, along with package requirements and save limitations.

I can answer questions about the rules, controls or included modes. When learning a new puzzle mechanic, do you prefer an Undo button for experiments or a move target to plan against?

Updated 5 November 2026: The full game is now paid. The browser sample stops after approximately five meaningful opening choices.

A life ends. Its record stays with you.

Which matters more to you in a branching story: a difficult immediate decision, or discovering its consequences much later?

Read the road. Build your crew. Hold the line.

I'm Ahmed from ANKH Studio. Cinderline is a dark-fantasy tower defense game: 160 gates across eight regions, 12 tower crews that branch into specialist paths, 27 champions and 9 powers. Every wave is shown before you send it, and when a gate falls the defeat card names the creep that broke your line.

How it was made: the art, music, sound effects and voice lines were made with generative AI (OpenAI image generation, Qwen-Image and Bria RMBG via Runware, MiniMax Music, ByteDance Seed Audio and MiniMax Speech), then cut, masked and animated by scripts written for the game. The code was written with AI coding assistants under my direction.

When a road doubles back, do you spend first on damage or on slowing enemies?
