Anyone not being able to load the game: Try closing your browser, opening it to your homepage (if you have one), and deleting your history/files. Maybe that'll work. Note: In IE there is an option to delete cookies, don't delete those. It's unneccessary.
Completed the game. Got 25 lives by end. No badge. I try to a play new level to see if that'd give me the badge. but on completion it just freezes on the end calculations thing, with the sound of points being spammed. Can't do anything but refresh. Also flash crashed twice before halfway through the game, making me lose my progress.
If you ever get that suicide truck nuke thing, pause while the caution sign and writing on the cargo is visible. If you zoom in, you can see what the caution and cylinder/cargo writing is. =D Cracks me up.
Ashrasmun, your keyboard might be to blame. Some keyboards cannot send more than a certain number of key signals at once. Get a higher-end keyboard or somethin'.
What sucks is that when i got to the trib cave after finishing the game, i couldn't beat two Crysophages... 'Cos they absorb light damage... So here i am stuck in a battle i can't flee, with no damage going either way (i get hit 0s)...
