Haven't decided on whether to make the code open source yet, but sometimes the code leaks into the Amethyst repo. Let me know if you want to be added to the "people to email" if/when it is open source.
Can you say anything about how the sound effects are generated? They sound like they’re procedurally generated rather than wav files. If so, does the code work on wasm32 and is it open source anywhere?
It’s actually wav files , for the menus I used a digital piano1, and for the hits I just hit my hands near my laptop mic. Then used audacity to remove noise and shorten some sounds.
1 fun fact, you can connect the audio out into the mic-in of a laptop – just turn the volume way, way down
