Twas okay.
I didn't really like the first Tankmen episode, and I have to say that this one wasn't a huge improvement. The jokes were too childish and immature for me to really find them funny, and as that seemed to be the central pillar of this animation, it sort of fell through.
Additionally the ending seemed to abrupt for me.
I hope that your next episode has sharper humor, but oh well. You certaintly get a lot of people to laugh and I'm just one out of hundreds. :P
On the other hand, the graphics and style of the animation were great. Practically flawless.
