One of my favorite things about this was the quick turnaround between death and restart.
With the explosion death update, it looks cool, but takes waaaay too long.
Also, tris should still give you more points in the higher region, and this should be multiplied by the multiplier as well.
I got to wave 18 and had 12,490 pieces of candy when I lost.
This got 31,000 points, just as a reference for potential hard badge getting since the game doesn't give us score updates. :)
I always support making WASD usable instead of arrow keys for those of us who are left handed or having broken arrow keys. Just giving players multiple gameplay options is always nice.
The whole idea of the guards' line of sight increasing as you move is clever, but ultimately broken. Since you can't do a darn thing when you're not moving, they might as well always see that far.
