Great job on submitting :) it was a nice idea, but I think a little too slow to really get going. Generally in a game jam you want to be aiming for 5-10 minutes of play time and you want to really hook people at the start. It feels quite aimless at the start before you get a feel for how you can affect the game, and by the time you understand everything properly it becomes quite easy. I can't complain too much though, it's a jam game and you won't have had much time for testing :)
Visually, it looks pretty good, though all of the colours are too saturated! I think you need to tone it down a little bit. https://mycolor.space is pretty good for picking a cohesive colour palette.
