Not a C64 game? So,
West Bank, a western-themed game
with a bank is no cigar either...
Hmm, let's break the pic and hints down then...
Western
A bank, so probably some kind of business game (but lost dutchman mine was also wrong) or some kind of advenure, although it has no typical adventure interface...
It looks early 90s
hmmm,
Only title I can come up with right now is
Wild West World...
please......
