Great concept executed with a lot of charm! The concept of mixing different penalties is a great take on the theme. I really liked that there was multiple routes to explore.
Sound, graphics and animations are amazing and you've utilized the pico-8 platform to its fullest, really impressive!
My biggest critique is that I felt the game was treating me unfairly at times. I would get stuck in a loop of bouncing on trampolines and being hit by the evil shadow for example, all while my package is slowly losing health. I think with some balancing you could turn losing the package from being a annoyance to a more fun chaotic moment.
I can see this core idea being expanded on further as well, with more level and penalty variations, but the game is really great as is with lots of replayability.
