Hi GingerLoaf !
Thank you for your feedback, I appreciate! :D
I used yellow/orange to indicate to players the color is changing, to avoid an abrupt change between green and red (and red to green) which could be too rude ! ^^
Green let you move and you are sure it's very safe until it began to change to yellow/orange. In yellow and orange you can move but it's at your own risks. :D
The only one color which make you lose life is the red one.
Did you reach the end of the obstacle course and saw the light ?! :)))
