Wow, the visuals here are really great. This felt really fun to play, with the ever growing mob and all the different destruction animations.
It would probably benefit from a few additional sound effects, say for when you break things, and angry noises from the crowd. I'd also recommend tweaking the jump physics a bit. You go up really high but the travel time is really short, which kind of makes it feel like the floor is magnetised! If you want to keep the jump height the same, I'd recommend increasing the air time just to improve the feel a bit.
Overall you did a great job, especially for your first jam. Keep it up!
