@oblivion60 You upgrade the bloody progress bar by clicking on the wrench that says "upgrade" on the bottom tab and then upgrading either anti-idle mode or idle-mode. You can complete quests and numerous achievements by doing this.
I think that mr.dinosaur is the best pet, because for 25,000 coins to feed him, you can get 250% increase of all boosts, rather than paying like 2mil for a bunch of 75% boost increases.
6273 pixels thrown. I'm surprised my pet's alive still. And 5800 pixels for my character. He's still alive? BTW (SPOILER ALERT) you can get Pillage the Pet by throwing it over 1337 pixels. You do this by clicking the pet (preferably when it is at the top of the screen, clicked on its legs or on the bottom of it), then moving the mouse to the bottom of the screen, then moving the mouse up as fast as you can (and releasing at the right time)
I think MMR is really hard for a laggy computer like mine because I press a button but it doesn't register until a few seconds later, so I almost always get an F (best i've gotten is a d+).
if the acid damaged the bosses over time, i think it would be the best option on the last boss (granted, you wont be able to constantly attack while dodging salvos and stuff, but still you have 180 dmg per second?).
