So what is it?

PoinpyDecomp is a decompilation of POINPY, a game made by Ojiro Fumoto that used to be available on Netflix. Decompiling means taking the finished, packaged version of the game and reconstructing something close to its original source files, so people can look inside it, modify it, or try to get it running on other platforms. To use it, you need your own legally obtained copy of the latest Android version of POINPY, extracted from its installer file using a separate tool. You then clone this repository and use another free tool called UndertaleModTool to open the game's data file. From inside that tool, you run a script included in this project, which does the actual work of pulling the game's assets and code back out into an editable form. Once that script finishes, the result can be opened directly in GameMaker Studio 2, the same game development software originally used to build POINPY. The readme credits the makers of UndertaleModTool, several other people who previously decompiled similar GameMaker games and inspired this project, and Ojiro Fumoto as the original creator of POINPY. The author notes that the decompilation may not be fully complete and could need further fixes, that it has only been tested on Windows, and that contributions and forks from others are welcome. This is a small, community modding project rather than a polished tool, built by and for people already familiar with GameMaker Studio 2 and interested in preserving or modifying a game that is no longer officially available.
