Hey! Thanks a lot for playing ....I'm glad you liked it :) ....if u time and angle the sword correctly, then killing the enemies is easy ...when I was making the game, I was focusing on what my son would love and he likes repetitive behavior, so I increased the health of the enemies so that it takes more hits to kill them ....and he loved it ...btw he has reached the final level now ....also i think FIRE is the most difficult one, even though it is at level 5.
