Liked it so much. Here's the point that you could implement/modify to upgrade it :
1: when the player lose (death animation + stop war dance animation)
2: with you font I dont understand fast that '5' was a five
3: implement a x2/x4 speed during fighting phase
4: create pixelized logo (like your current art : (health, gold, maybe upgrade too)
Art is so cool, concept is crazy, gameplay work very fine, and transition are simple but fire. It's my favorite game for the moment !! I hope you'll get a nice classement !!!
