So I sort of used the Apocolypse weapon, the one that destroys the outside bubble, and after using it, my tank just sat there, supposedly in the middle of the bubble to the right of the one I blew up, with random bubbles spraying out from all sides of my tank, can't move or anything. Cool.
The game is a little luck based, but if you're lucky enough to get a "hyper gem/???" where you combine 5 gems together, and then use that with a counter gem (I got 396% when I did it) and hopefully the boss will get one or two attack gems (my win the boss had a normal attack and a special attack, I was also lucky enough to get to get a defense set as well which was 100% defense)
Plus if you'd like to keep this up.
Got the "Too Cool for Light" badge after restarting my browser, having the shades on from first mission without taking them off, and getting all cards, not sure if it's what's needed, but it's what worked for me.
Don't know if people are waiting in place, but you need to wait until it gets to the beginning again to get the badge, it's not immediate. It's after the Nyan song.
It doesn't say it in this one, but it does in the second one, if you used the walk through, then you need to close the walk through and refresh the page and re-do the game again, that's what worked for me.
