Definitely late to the party, but this game has crashed twice on me (on Linux -- thanks for supporting that, by the way). Bug report is
Runtime exception!

Both times this happened, I had a lot of vamp minions. Dunno if that's relevant.
Also, the file "Dusted.wav" is referred to in the code as "dusted.wav" (a different bug that I "fixed" by renaming the file).
That aside, this is certainly a fun game! I've seen the premise before, and this is a very nice realization of it.
