Ok, I tried to load this game on chrome on my laptop. Didn't work. I switched comps, and I still am on chrome. Doesn't work. I don't suggest using chrome for this game.
The "Erase Data" button in the "Options" menu NEEDS a prompt that when clicked reads "Are You Sure?". I accidentally erased my data when I was just trying to turn off the music. + if you agree
Achieveing challenge 6 is fairly simple too, grab your single small orb and hover directly into the center of 1 large orbs (make sure your in the center of the orb for this to work) and start to click non stop. If you do it right then you should instanly kill one of the large orbs, leaving to plenty of small orbs to use as a shotgun, running right up next to other large orbs and destorying them instanly. Just try this strategy a few times to see what I mean.
Hidden award is gotten by going above the "os3" award and to the right of the "Awards" sign at the top. Just hover your light from your cursor in that general direction and you'll see a blank spot where your light isn't working. Just click on that black box for hidden award.
May just be for me, but I can have a perfect round until the last stage (6 cannons and smasher). I think the music gets delayed then because the bass drum and claps are off beat from the shots and smashes. I can never get impossible badge due to that
it is a bit laggy so it only records about 2/3 of your time if you fire a lot
I know this because i got 598 seconds but i timed it and i played for 14 minutes
