10 Million Points Problem

"It is actually impossible to reach that high in standard Drillimation gameplay, as most players generally score around 1.5 million points."

- Susumu Takajima, with an interview for PC Gamer

The 10 Million Points Problem (１０００万点の不具合) is a glitch that appears in Drillimation games in the Driller Engine 1 Era and the Driller Engine 2 Era. The score counter stops when the score of 9,999,990 points is reached, making it impossible to score more than 10 million points.
