SEGA Golden Gun (Try to clear with only 1 coin) but failed

Played at Fun Planet, 3rd floor, Central Plaza Rayong. Played on 5th October 2019 Life start 3/3. No premium start chance No exchange chance ..... I do a rapid fire by myself to avoid the damaged and take more score. Quick reload is an important item to beat the game easily. So I try to make a score more than 40K and buy ATK power as many as possible. Unfortunately, Not enough score to buy a bonus life in every shops. I can't clear this game without continue used for now. Maybo I can make it next time. ...
