Very cool idea / mechanics! The dialogue was fun, and I liked those in-between moments because they felt like a nice break from the craziness of each wave. The style of game isn't something I usually play, and I found it difficult to master the controls and defeat the waves (which might also be a skill issue or unfamiliarity with the genre on my part).
Even so, there's a lot of humor and charm here, and I appreciated the tone of the dialogue. Nicely done!!
