The art here's quite good, especially for a Pico-8 game. I also like the concept a bit. The main problem is that it doesn't feel like it relevant to the theme at all? It's not shown anywhere that the main character isn't a hero or that they're some kind of villain. The physics are also slightly weird, but that's probably again because it's a Pico-8 game. The sound effects also really hurt my ears.
Overall, the game's still pretty good, and should definitely be improved upon in the future.
