Document of the rules from the game

[es-rene99]

We need to have documented which are the rules for the game, here's somethings we need to clarify:

• What makes the timer increase and decrease? Personally I though the timer could increase if the player answers one operation correctly but maybe it will be better 3 operations.
• Which are the tools the monster will gather as it levels up? Also will the player keep the tools for the next play rounds?
• What happens with the monster once there's a game over?
• How often will the monster increase level? I was thinking it could by every full minute.

There are other things that may need to clarify.
