Good game with MANY problems...
Here are the ones I spotted:
Music is VERY repetitive.
Museum is impossible to get into, and when you try it takes ALL your money.
You cannot buy a car.
You cannot steal a car.
There is only one secret item possible to get.
You cannot take cop jobs.
There is nothing to do with the drugs.
Enemies don't fight back!!
You cannot get promoted at the "business".
You cannot make any money working at the "business". You just lose health.
You cannot rob the "business".
I think that covers it. Despite these problems, it really is a pretty fun game.
