Pretty good - took me a bit to figure out what to do, at first i was just spinning waiting for enemies, until i got out of the game, and then read the page tutorial. Small tutorial would be handy!

Love the sounds, graphics, animation.

My only concerns at the moment, is movement is quiet difficult. and also the coins dissapear way to fast.

Im trying to kill a hoard, and they dissapear before i can collect them.

A simple solution would be eihter, make them last longer, or automatically score them.

D or Right arrow to spin Right.

A or left arrow to spin spin left.

Hold both to Move forward. 

See if you can find and kill the boss!
