What a fun shooter. It was nice to find a classic zombie horde game here. The variety of weapons was great for changing up tactics and it seemed fairly well balanced. I didn't do nearly as good as you - I got 484,700 points.
But yeah, that was super fun.
By the way, if you ever feel like trying to set up a leaderboard online, give loot locker a shot. I set that up for our game, and it's pretty easy to use. Ours is not working perfectly, but that was mainly my part for missing one line of code... ah well D:
Regardless, great job!
