I love the idea of this but the execution is lopsided. The difficulty falls on the 'unfair' side of the fence and after a while I found myself not wanting to keep trying (ex: the Dash is almost worthless as I end up dashing INTO fire I couldn't possibly have seen from a different mob I was avoiding). I like challenging games but the fun ground to a halt in this one.
Also, you guys ran into the same bug I did; Godot Web build have this weird issue where Audiostream slowly loses volume every time its used. I ended up having to constantly create copy instances of Audiostream.
