fun idea, but i think the enemies have a little bit too much health or you don't deal enough damage. Maybe a ranged weapon attack could help? I couldn't get past 10 experience ):
Thanks for the feedback! You actually kill enemies in 3 hits on Lv3 and 2 hits on Lv6, and enemies start dealing less damage to you as well! Unfortunately, the game is a little hard in the beginning, so it's hard to actually get to the part where you feel more powerful!
