nice work on this. Excellent range of enemies.
I was a bit disappointed by the crossbow :P. Heavy hit, but very slow, suppose that's the trade off. I had some bugs with it where it didn't fire at all (while holding mouse, or by clicking) off and on until I died.
My suggestion would be to ramp up the pace of things to 11! :).
More and faster enemies, much quicker fire rate.
But I did enjoy it! nice set up!
