I really appreciate that you have done everything on your own. I can see that a lot of work was put into it, but as you already mentioned, art and music could be improved or outsourced if you want to focus on coding.
Anyhow, I like the game. It's fun to watch it, but it's no real challenge to "win" if you can tweak all the parameters. If you keep working on the game, maybe think about several levels, where some of the parameters are pre-set and others can only be changed in a specific range.
The graph is really nice and gives a good indication about the behavior over time.
Feel free to checkout our game too ;)
