Absolutely awesome man :) !! Everything feels juicy and so satisfying ! The screen shake is not over the top, just enough to make each shot feel great, and the particles that fall to the ground is a wonderful little touch !
Also, the character designs and animations are delightful, really I'm impressed ! Not to mention that cool little intro scene !
Didn't reach the 10th wave I'm afraid so I don't know if there's a boss, but what I did see was top notch, keep it up :) !
