As always, I love your art and I've always been fascinated by the work you do on the engine (first used with Dr. Kimmy, right?). I also love that we both went with the theme, but still managed to go in unique directions with it.
The belt upgrade (especially the helicopter) was incredibly fun. And I feel like this has been the most balanced of yours in terms of difficulty that I've played.
Overall, I loved this game. Its just so fun and funny!
