We did get a few general questions that are not spoilery! Here are the answers.
Actually there is no plot significance at all! Frisk talks in both sentence case, all caps, and in lowercase, depending on the situation. The lowercase “ah!” is supposed to be a bit understated. What a versatile speaking style!
Good eye! We completely changed the fire as well as made some adjustments to the overall look. We think it looks cooler this way, and we can work faster this way too! We have actually changed the line art and background style a couple of times to better suit our process. And of course, our art is always improving with practice too!
Actually, this latest fire is the fastest one yet! We went through several iterations of fire before deciding on this energetic stylized version.
I don’t have an answer for you, but I do have this requested coffee artof Chara getting their ass kicked.
It’s actually neither. Chara upgraded from that old blade a long time ago.
