I'm loving the game!
I didn't read any instructions, and playing on the browser, as I went to choose the Wizard I simply got utterly demolished with my staff firing only to random directions, all I could do was have the goblin bounce off the staff and pray for the fireballs to reach him, but after reading comments and instructions I changed settings from Gamepad to Mouse & Click it turned the game into an enjoyable experience :)
A friend came by as I was playing it and told me to leave props to the bouncing toupe of the Archer, she got it to lvl 13 while screaming all the time while running from the little goblins, hilarious experience!
Very polished and fun, Nicely done!
