Mars Roverflow

You are piloting a rover on mars. Your objective is to collect as much data as possible, but there are aliens who are trying to overload your memory with viruses and useless data. Discard the viruses and save all data pertaining to carbon without overflowing your memory. 

You only can have up to 8 items in your memory at any time. Your score goes up for correctly saving data that contains the word 'carbon'. Your score goes down if an alien catches your rover and if you try to save data that doesn't contain the word 'carbon.' Your score will also slowly decrease over time. 

Controls:

WASD to move the robot

Double click on data to open it (necessary to check for the word 'carbon')

ESC to pause the game / open options

backspace/delete to delete a selected data item
