Analysis updated 2026-05-18
Study how a falling sand pixel physics simulation can be built in Unity.
Watch the linked gameplay video to see an early prototype of Noita-style pixel destruction.
Use the project as a starting reference for building destructible terrain in a game.

No build or setup instructions are given in the README, requires opening the raw Unity project.
PixelAlchemy is an early experimental prototype for a video game, built with the Unity game engine. It belongs to a genre sometimes called falling sand games, where the world is made of individual pixels that behave like real materials: sand falls, water flows, fire spreads, and so on. The project's description says it takes inspiration from Noita, a well known indie game praised for this kind of pixel by pixel physics simulation. Based on what the README says, the project focuses on three things: simulating individual pixel materials in detail, letting the ground and structures in the game world be destroyed piece by piece, and experimenting with combining spells or magical effects in a roguelike style, meaning runs are meant to be randomized and replayed rather than following a fixed story. The README itself is very short and mostly consists of a screenshot and a link to a gameplay video posted on Bilibili, a Chinese video platform, under the creator's handle RepinSKY. It does not describe how to install the project, what Unity version it needs, how to build it, or what state the prototype is in beyond being an experiment. There is no license information, no setup instructions, and no list of dependencies given. Because of how little the README says, this looks like a personal or hobby prototype shared mainly to show off early gameplay footage rather than a finished, documented tool for others to build on. Anyone interested in it should watch the linked video to understand what currently works, and expect to explore the Unity project directly, since the README does not explain its structure or how to run it. This is best suited to game developers or hobbyists curious about pixel physics simulation techniques, not to non-technical users looking for something ready to play.
