That was AMAZING! I loved it!
The music was great. From what I gather from the credits, the tracks are not commissioned and were pre existing? If that's the case it's so impressive. Perfectly chosen to fit your work. The way the march worked with the effects was particularly good. And the ending credits song felt like it was made for the game. Such a great fit! Also, on the subject of audio, I noticed a few usernames in your freesound.org credits that I've used as well which made me smile. How good is freesound! :D
I love the art. Kind of high res but non-anti-aliased pixel art (not sure how to even describe it, but it's rad). Your style is so distinctive.
The movement and animation choreography was superb. So expressive. You depict so much with so little. Absolutely loved the fight scene where Bucks was dismembering all the rabbits, that was so awesome :D You've inspired me to think about trying more movement in my stuff. I feel like my approach is very static, I need to experiment more.
The story was so entertaining and genuinely funny. Your comedic timing is great. And then also genuinely heartwarming and bittersweet as well. You have awesome range. I haven't played the main game (will def have to remedy that) and I felt like maybe I was not quite understanding a few things. But all in all it still worked pretty well as a stand alone story.
The GUI was super good. Lot's of nice little unique touches. And I really liked the 'out of game' interludes. That layout was really well done and used to great effect.
All in all, fantastic stuff. really well done!
