This is quite a piece of work!
The interaction systems are complex and enjoyable to watch unfold and there is a mastery of procedural systems at play here.
It's difficult to critique the work since it's at an early stage, what you have here is the basis of a concept that has a lot of possibilities. What's important is that the implementation is proven to work and you have a method to scale these systems if you wanted to.
I would take a step back and come up with solid theories on finding the fun of this system and focus on it with a razor sharp precision. There is a danger of working and working on this to no end since the systems are infinitely deep and complex.
It will take careful design considerations to push this prototype to something truly special.
Amazing work, it's an achievement that you were able to execute on this within a week.
