can you post a downloadable version plz?
There is no downloadable version, only the web build.
It would not be trivial to make a standalone executable because I did not make the game in a game engine, but instead programmed everything in C (almost 2k lines of code) and compiled it as a WebAssembly (wasm) with Emscripten. I wrote some JavaScript "glue" that handles I/O, while the most of it is going on in the wasm part, which in each frame calculates the game logic and information about color of each pixel and which sound should JS part attempt to play if any (in technical terms, it returns a pointer to a memory address from which JS reads all relevant data for the current frame).
Making a standalone executable out of this would involve writing additional code which would handle I/O the way JS "glue" does in the web build (but probably more complicated than JS). That code would have to use a library, probably SDL, to make it happen.
