A lot changed in the moments I were gone, wow. It looks like the SFX bar still has the issue of changing volume to a much higher scale than it should and is effecting global volume, but the other two bars are fixed.
Also, your dev-log has the old version of the game. You may want to edit it.
All looks good! Hope to see saving in the next version, and maybe more layers.
For a first incremental, this is lovely.
Best of luck, and cheers. Will check in later.
