I really like the characters, they're fun and they each play off each other pretty well. Dalia is the chill laid back kinda ditzy one, the friend with the glasses is the negative but secretly caring guy, and Kaiser is the innocent joyfilled main character.
I am a bit confused on who was who, since they barely used each others names. Not to mention the friend with glasses wasn't mentioned in the credits anywhere, only after rewatching the cartoon 3 times I noticed his name is Levi. The backgrounds are okay since they serve the animations purpose, but since they are 3d in some scenes the characters look a bit flat. Sometimes the rift was not moving when it was onscreen and the timing and lip sync is off in some scenes. With how much cracker jacks were mentioned (since they directly influenced the plot) they should definitely sponsor you haha.
My favorite bit was definitely the first scene, the dialogue is funny, the poses were really iconic and the timing was better in the beginning. The boarding/art direction is really good there, I was getting ian jones quartey vibes from the art style similar to how the first few episodes of steven universe looked (since they were boarded by him) which is a huge compliment, and the voice acting was great for those lines too, they really nailed it in that scene. The helicopter argument was funny too though. Despite the flaws I really like it, great job on this.
