The best theme for this game is Portal 2, An Accent Beyond, just mute the music(but who would, it's already epic enough) and make a new tab and put the song on. Best song to kill gummy bears with.
Here's a little glitch. Go to level 29, and place the drill right next to the power button, make sure it's facing towards it. Then, turn the power on. The power button should fall off the screen, but while it's in midair press the power button before it goes off screen and it'll teleport back to where it was.
Laggy. I know people are going to vote this comment negativly, but I'm just saying, make a setting where the graphics aren't as great so the lag decreases.
The funny thing is, this reminds me of the portal series, GLaDOS trys to kill you,and she's a robot, and there's a test subject Chell, the robot, just to let you know, and I'll probally get flagged as spam, but I don't really care.
