Hmm....
First off right off the bat I love the Art Style.
The characters have an nice slick hand drawn look to them.
But Gameplay wise hit and miss... at first I had a blast shooting enemies,
but it got boring real fast. You have the right idea but I think the gameplay should be faster something adrenaline pumping. In my opinion.
Also controls could be reworked. Have the mouse control the character, left click could be shoot. and right click could be jump.
Overall.
++ for the artsyle
-- for the gameplay
But really I don't hate it. I'm just not in love with it.
I would love to see more though.
