I win! It took me 4 tries I think. It was fun and I concur with everything the person below said, I really like the artstyle, the "narrative arc" with the extra paths opening is great and I got delightfully surprised by the jumping enemies (in level 8 or something?) who defeated me before I eventually won the next time (I locked the enemies from level 10 behind a barricade and will never know what they would propose).
Appreciate the thoughts, I'm glad the jumping zombies weren't just confusing and annoying; I really wanted to fit in some more out-of-the-box enemy behaviour, for better or worse.
I never even thought about people barricading the last wave, which is pretty funny once you know what it spawns, the barricade feature itself needs a lot of work.
