I think money is going to be the only thing you need. I made a key hack and pressing M in the main menu adds 5 $. I got my skills up to max and bought everything after half of the first season.
The problem is just that there is a submit function and it seems i have to complete the game to test if it actually does something and eventually disable it. Did anybody ever played this game long enough to actually submit a score or something, it really gets boring after a while.
So i am not going to upload this.
