Wow! That was super constructive and useful. I'm sorry you had so many issues, really it's as you said, webgl is pretty bad. We've been taking the feedback into account for the update. Mostly about the stuttering and freezes lol but also about how to use the flares. We knew it wasn't clear, but we ran out of time to playtest and tweak them (they dispel nearby shadows after 3 seconds but they should last longer). Thank you for your patience and for playing until the end!
