This is an experimental game where the backend is written in Go and compiled to Wasm. Honestly, it started from a desire to learn about import maps but then I didn't really feel like implementing anything hard in JavaScript. Then the frontend code was so simple I didn't need any dependencies. So overall, a bad pick for learning import maps, but great for Wasm!
I found this page to be quite helpful when writing Go for Wasm.
Feel free to read through the source code and find me on twitter if you have questions!
