Great game, though a sort of auto fire would be useful to those that can not aim fast enough. It certainly deserves 5 stars and I can't wait for the next part. The use of ship 4 eludes me a bit as ship 3 is faster in it's attack so easier to use in battles as with the upgrades it easily outperforms ship 4.
I had to reload the page as my browser was annoying and the tutorial is gone. What kind of game has a tutorial that only works the first time you load the game?
Second kill is lit candle on the bed. A fun way to introduce someone back to hell. For the extra's I found the carving pumpkin with knife and lit candle (excludes firey death as candle is lost) and Riley likes to smoke a cigaret. According to newgrounds there is another secret, but haven't found it yet.
