for the eyesight test(colour test) here is a small walkthrough:
1. hexagon is the bottom left. 2. circle on the right. 3. the small light on the truck at about the middle across and about 1/4 up
if you play a different game or whatever while this is on, do not have it in a new tab or the game will pause until you return, so open the new page in a new window
for those that rate this game bad just 'cause of the time blocks, heres a tip. after you hit the block press the arrow key in the direction of it again to destroy it instantly
thank you I won't do it next time :)
