ScoreKeeper

A devious game for those skilled at quick math. All you have to do is keep the score for the hero dungeon-crawling below.

This game was created for the #gbjam (gameboy jam 4)!

Note: I had much less time than even the jam allowed for, as such, the game is quite minimal; I did not even have time to include some rudimentary sound. However, it is fully functional as per my original intended design; it's just also insanely hard for anyone not skilled at quick addition (I'm bad at my own game)!

Here are the instructions:

Arrow keys (or WASD) to move/climb.
Num-Pad to change score numbers.

Snakes add anywhere from 1 - 9 points.
Bats add anywhere from 10 - 99 points.
Zombies add anywhere from 100 - 999 points.

Once the hero reaches the end of the level, you have until the timer hits zero to match the keeper's score to the actual (hidden) score.
If the timer reaches zero before your score matches, you must still match the score (or see note below), but you will lose a life.
If you fail three times the game will end.

Good luck!

Note: You may press 'R' while on the game play screen to restart the entire game.
