I legitimately got #2 on the All-Time High Score list for exp gained at once... but then it was removed? Lame. http://prntscr.com/6tx5ib The proof is in the pudding. Well, that link, at least :p
I beat insane mode; the hardest one was really probably #9 (the giant cyclops thing with the minions) because all the minion bugs' shots are so hard to dodge. The Kraken was hard for me until I had the right equipment, which for me was: Needlessly Hot Pot Suit, 2 Enemy Info Goggles, 4 Final Tech Gloves, 1 Final Tech Armor, and 1 Lucky Cat. I actually only had 2 Blasting Pumpkins and 1 Airball 10 000 for my droids because I couldn't afford the expensive ones,But I didn't notice much of a difference. I'm not sure if this is the best way to beat it but it worked for me. 5/5
A brick fell off the bottom of the screen milliseconds before I managed to place the 99th brick. I don't know if I'll ever be able to emotionally recover from this.

That noise is what happens when you set the volume to NaN, and then attempt to fade it out.
