The revolver auto-shoots so fast that I can barely get 3 clicks before having to reload. If one holds the mouse button it'll empty the cylinder in near world record time.
You have a good driving core mechanism, but now there needs to be a game.
Either go upgrade complete or build a story for a purpose to all this knight squishing.
Bug: Got up to lvl 5, ran out of time, and got charged $250. The clock didn't reset but my 4 out of 5 deliveries did. About 10 seconds later, another $250 with reset. It kept doing this till my $2500 was gone. Now I'm stuck with 5 deliveries in about the time it takes to get up to speed. For now this bug makes the game unplayable.
Besides that, the game is really cool.
what browser are you using? Firefox, Safari, Internet Explorer? Thanks!
UPDATE:
It was broken in Internet Explorer (IE) but should be fixed now. Thanks for your patience!
Pretty good start to a choose your own adventure type game. I like the mythos you are building. I would like to see more choices at points, instead of just clicking 'ok' to continue at the end of a question. Maybe even have some choices have dire consequences. Having a button up in the corner to take one back to the main menu would be nice too.
