Nice art! Gameplay has caught my eye, it's unique (at least i didn't see such mechanics for a long time). However, i think it needs more freedom of movement. After some playing, i wanted to move or have enemies approaching from above. It may be my personal preference tho.
Nevertheless, i had fun playing it. I even got 378 as a record (i think it could be better, if my browser didn't lag ). The whole artstyle, including graphics, animations and music were complementing each other and, as some other fellow commenter said, it feels like a good old flash game. I appreciate that.
