MSX Calculation Game

The game helps improve mental arithmetic skills. It is written entirely in pure MSX-Basic and was programmed on a Philips VG-8235 MSX2 computer.
The objective of the game is to solve as many randomly generated equations as possible within the given time frame in order to secure a spot in the Top-10 leaderboard. The time frame is graphically represented by a red bar that continuously fills from left to right. The game starts very simply with the arithmetic operations ADDITION and SUBTRACTION, and the number range 0-9. The difficulty level increases after every 9 correctly solved equations, with the number range multiplied by 10.
Starting from level 4, all four operators are used.
