Holy shit. by far the best entry i played yet. gorgeous sprites, the music creates the perfect mood, and the gameplay is unique and has quite some content.
The only things i can criticise is for one the lack of a tutorial / a simple "controls" page. I didn't know you could kill enemies until i was like 10 minutes into the game :D.
The other thing thats slightly annoying imo is that the movement feels too slow. it could be all around a little snappier. A little more responsive.
All around a well polished and rounded game! Congratz!
