Thankyou thankyou!!
Funny you noticed that about the intro comic as it actually was drawn as 3 separate pages that I coalesced into one because I put the "Of course Ms. Ruby" reaction on the wrong page and it broke the flow ;-;
I agree that some thicker outlines would for sure benefit it!
And I like the idea for the audio cue for the low crystals, would definitely prevent some self-inflicted demise :P
