Amazing for your first game jam submission! It simple and fun! I would recommend if you plan on updating the game after the jam is that you either zoom out the camera a little bit of add an option to toggle the zoom. The screen is really busy and it’s hard to tell where you have to go. And also adding an outline to the vermin or a different color would help. The green they have now blends with the background. Still it’s a very good start! Great job!
