Yay! Thank you. I got a buddy to play it too and he played it through a couple of times (and blew my hi-score out of the water - damn lol). We had a bit of a chat about new features, maybe fire arrows as an alt-fire so I can have an excuse to throw in some more lighting effects.
Thanks again, really glad you enjoyed it - the encouragement is really useful and I'm going to take this one further starting this weekend.
