Wow this episode was massive, I really like the characters and the writing, so I wanted to talk about those first.
The jokes, and style are funny and entertaining, it's reminiscent of eddsworld (which I know you have a history with) it shines through. The story is well written, the way both A and B plots escalated and the scene transitions going back and fourth are well done. I love the characters because similar to eddsworld, it feels like you're going on an adventure with friends. Each character with their different personalities and quirks are a joy to watch. I think the voice acting is great, they can play the characters well, but the voice of Dave is a bit different in quality, it's noticeable enough that it takes me out a bit. Caleb is so fun to watch, he did a great job voicing his character.
Although the writing, characters and voices are amazing, I have to admit the animation is of varying quality. Unfortunately there are scenes that had me actually frowning while watching this. Every time a door opened it looked questionable. But the scenes that are animated super smoothly well are above and beyond. I know a movie of this length needs all the help it can get, but if you did downscale to 10 minute episodes I don't doubt the quality would be much better, throughout the entire duration. The art and backgrounds are exceptionally good which compliment the simple style of the characters, which is fitting. The end credit art was gorgeous.
The background music was really cool, you had a good mix of bgm and music artists working on it. I think the metal soundtrack was too loud in the scenes they were in (Including the montage) but the rest were moderate volume and complimented the scenes. Like satans son talking to Caleb, or the election of mayor Anna.
Overall this was awesome and the references (like the minecraft painting and saw on the tv) were the cherry on top. I am excited to see what else you guys make.
