For a game jam, this is really excellent game! This works on multiple levels. It's actually quite a sophisticated design for a short time of development--we love the two-part gameplay. The aesthetics are consistent and really fun. The sound is good too. We found the game well balanced, given your short development cycle. And we loved the tone as well. This is a game that could certainly be developed more with different level design and more mechanics with different kinds of currency and power-ups. But you have a great core game loop. Great job!
