I liked music and graphics. Using guitar as a weapon? Idea seems fine but all your guitar do is shooting projectiles, you could add some special abilities, like playing right tune to kill specific type of enemy or playing something to make temporary shield around you or boost your speed. There are many possibilities. Anyway i enjoyed your game and i hope i will see more expanded game :)
I like the idea for the theme, fighting orcs with your guitar! The controls could use some work though, I sometimes got stuck on the side of the terrain and I could jump after falling from a platform. I really like the look of the sprites though, very nice graphics! Well done!
What Zeriv said, the weapon definitely seemed a little bland, adding different chords or notes and playing after the other would've been really cool, loved the pixel art, trees were really cool.
I thought that the graphics were ok although the transitions between land/water were sudden and in need of some blending. I also found a couple of bugs where the player could stand on the orcs / in trees and once fell through the ground and into oblivion. Well done for creating your game!
Anyway i enjoyed your game and i hope i will see more expanded game :)
