Hmm. I still think these non-action episodes aren't really the best, especially when it comes to animation. This episode felt like if it was animated by someone doing a short in Garry's mod. Actually, I think the teacher's (non-)animation was the best. Seems like the creator can't really animate anything well just fight scenes. I mean, sure, animation is hard and takes a long time, but it just feels off when those scenes seemingly needing less animation are worse than those that would need better skill.
On the other hand, I do like that there seems to be some character fleshing out going on, but still, they seem to be very bland. I'm actually afraid of this show being cancelled (if there's such stuff on that site) before it can show off its true potential.
