Awesome but huge glitch
Eh, little glitchy! I went straight for the Very Hard difficulty, and once there were more than one enemy on screen, had some interesting glitches -- I'd type out the word of the closest enemy, and despite typing a word such as TALON, I'd kill an enemy with IOTAS. I played several times to make sure I wasn't just seeing things, but sure enough, I could start a word, and then basically button-mash and kill everything on screen except for my targeted foe.
The game is so great, but that glitch really killed it for me!
