Best I did was 45400 (wave 14) so far.
I am really happy I could use the arrow keys to move, because with an Azerty keyboard switching to Qwerty to move and switching back to be able to type words would have been insane.
I think the concept is kind of silly so obviously I love it.
The game is fun, the controls feel good, the different types of enemies are fun to deal with and the difficulty is fine, as you advance you'd better not miss typing a word, which I did so I died.
Cool game, thanks for sharing.
