Glad I found this on a rainy day at the end of work when I'm sitting around doing nothing :)
A suggestion: It would be nice to have the option of different windowed sizes, fullscreen is a bit giant on my monitor, but the window is too tiny. This would allow me to keep the fire going while "doing work"
EDIT: Another idea... a mute button! I love the crackling but sometimes I need clean audio (i.e. when composing music)
A big new version has been uploaded with a mute button and different window sizes (Press Z for zoom). Also more and better color palettes to choose from.
I hope the window position (bottom right) is good for now. I will add a way to move the window without utilizing the windows title bar in the next update. I want to keep it borderless for aesthetic reasons.
