:When the player moves into a room containing enemies a battle will start. The battle will be carried out by means of "clashes."  Each clash represents a possible attack or action and will be shown as a math problem that the player will have to solve. The player will enter the answer in PC Mode by clicking on the text field at the bottom of the screen and entering the numerical answer using the number keys on the keyboard. In GB Mode, there will be a number pad on-screen and the player will be able to highlight a number or symbol with the directional pad and select by pressing the check button on the right side of the monitor.

:When the player moves into a room containing enemies a battle will start. During combat, the player will choose from a list of commands to execute. Different commands will do different actions, having the player solve various types of mathematics. The game’s input may change depending on the type of answer that is needed. The player must answer as quickly as possible in order to optimize the amount of damage they deal to the enemy. Losing a battle will reset the player to the latest checkpoint position (usually the start of the current level), and force them to backtrack a little. Winning a battle will grant the player rewards and money. These will help the player to survive throughout the game. A notification screen will appear either way displaying the outcome of the battle.
