milidogs wants you to accept strings which are odd numbers when interpretted as binary strings where red is 0 and blue is 1. So if the robot is red,red,blue,red,blue, you interpret it as the binary number 00101. You can easily check if a binary number is odd by looking at the last digit. If it's 0, its even, if it's 1, it's odd. So, you just need to check that the robot has a string with last color blue. Luckily you've probably already thought of how to do that for other puzzles.
Reminder in case people are still having trouble: if you don't receive a badge that you should have, in any game, you can send a screenshot of your progress along with the name of the badge to [email protected], and we'll help out as quickly as possible.
Also, thup is awesome for this game and checking out his code/stat submission :D
The existential implications of this mrcredsalexian interpretation of life are manifold. I feel it connects on a deeper basis with my own life than anything else I've yet to come across.
