Also, to those having input issues: As far as I can tell, it's the keyboard, not the game, that causes these issues. I was able to replicate them with an old crappy HP keyboard, but my Apple keyboard works fine.
Bugs out half the time when you get hit by a shuriken. Then, after everyone but the thrower got through, he just kept throwing forever. This is very disappointing for a challenge and achievement game.
Yes, ummm, the monsters are often unavoidable, making this pure luck, and therefore, an annoying game, 1/5, give like 20 lives if your going to do that.
