Thanks for the reports!
In this new update I hope I finally fixed that issue with the audio cutting out around treasure. Been in there since the beginning. It’s quite a hack: I think it’s a bug in how Chromium handles audio parameter automation. We can use an FFT to detect audio crashes and then rebuild what crashed it. So now the wah effect on the treasures might stop for a moment, but it’s so much better than the whole game going silent.
I think I’ll have a solution for getting stuck in the terrain next release. So far I think it’s related to frame drops and how I’m using delta timings for physics and collision detection. Probably need to handle or check something differently.
