A small browser Breakout-style game with spin and quasi-physical ball physics, which the developer says was fully vibe coded with DeepSeek and ChatGPT; the levels are hand-made.

Rights holder / original work: Breakout (Atari)
The developer describes the game as a “breakout clone”, and the easy and hard versions are titled “Breakout with Spin”, using the name of Atari's 1976 game. The levels are the developer's own and no source mentions Atari assets; no source mentions a licence. (GitHub (brontosaurusrex))

About Physical
Physical is a short brick-breaking game in the style of Breakout, which its developer calls “a little physical breakout clone”, made to be a five-minute browser game that is actually fun. The ball picks up spin from the paddle and bounces with what the repository calls quasi-correct physics, and the developer says the physics engine runs at 240 Hz regardless of screen refresh rate. There are three kinds of bricks: common, unbreakable and magical, which trigger power-ups; one commenter mentions effects such as anti-gravity. Levels unlock as you go and can be switched with Page Up and Page Down. It plays with the mouse or keyboard; on phones a menu offers four control types, including tilt, though the developer says mobile was barely tested and iOS not at all. The developer, brontosaurusrex, says the game is fully vibe coded with DeepSeek and ChatGPT, while the levels were made by hand. Free on the developer's GitHub Pages, with an easy and a hard version and a beta of the next version.
How it was built
VerifiedThe Show HN post says the game is “Fully vibe coded (deepseek, chatgpt)”, with the levels made by hand; the repository README says the project was an attempt to vibe code a Breakout clone with quasi-correct physics. DeepSeek, which is not in our tool list, is named alongside ChatGPT; the post does not say which of the two wrote what, or which models were used. In a reply the developer says this was about the fifth internal version of the physics.

Vibe coded with DeepSeek and ChatGPT by the developer's account, with hand-made levels. The game pages load a WebAssembly module through Go's wasm_exec.js loader, so the game is written in Go and compiled to WebAssembly (observed). The developer says the physics engine is decoupled from the refresh rate and runs at 240 Hz; a v8 beta posted on 4 Aug 2026 adds ornamental debris.

“Fully vibe coded (deepseek, chatgpt), levels are human made with some amount of love.”Verification notes: The AI claim comes from the developer's Show HN post of 31 Jul 2026 (14:43 UTC) and is backed by the repository README, which describes the project as an attempt to vibe code a Breakout clone. ChatGPT is recorded as the tool; DeepSeek is named only in the usage text because it is not in our tool list, and the post does not say how the work was split between them. The brick types, mobile control options and testing status come from the developer's replies in the thread; controls, level switching and the 240 Hz physics from the post. Cheat and debug keys described in the post are not listed as features. The page at v7 is titled “Physical”; the easy and hard versions linked from the README are titled “Breakout with Spin”. Go/WebAssembly was inferred from the pages' Go wasm_exec.js loader. The developer reported 82 visits in the first day from an analytics counter; this is not recorded as a metric. The Show HN post is the earliest dated mention found, so no release date is recorded. Team size and location are not stated. The game was not played through.
