Ground rule:Don't buy hardware unless desperately needed.
Since there are many strategies to go through a level, I am afraid I can't give you exact instructions.
What you can do:
- Sell all hardware and buy back only what is really needed (and keep this in mind)
- Use a cheat code for a little bit of extra money (email me if you don't know it)
- Restart the level / game.
Remember: This is a hacking game. You might have start all over and go through several attempts
It's not a racing game where you will eventually reach the finish line
