Thanks for this it’s really useful feedback.
I’m currently investigating the sound issues. It’s seems to be an issue somewhere between FMOD and WebGL. The web isn’t one of our target platforms but I still want the HTML5 demo to put it’s best foot forward. If you want an artifact-less version please check out the demo hosted on Steam.
I’ll introduce a tutorial level to better explain the aim of the game too.
Thank you for the big reports too. I’ll investigate a way to limit user input to hopefully mitigate crashes. And you’re right, you shouldn’t be able to force blocks through walls!
Thanks again for your feedback!
