Made it to "they aren't" on the first run, which I believe was the 4th wave? Reminds me of Typing of the Dead. Overall pretty good, though I cannot imagine getting to wave 10 with this difficulty curve.

The difficulty curve is shockingly hard. The furthest I've seen someone go is wave 5. We are planning to update the game later on to smooth out the difficulty because there is other content in the game that won't see the light of day like backwards walking zombies where you have to type the word backwards. Nonetheless, thanks for enjoying the game :D
