Loved the art! I wish I found out that I could just hold LMB to fire a bit earlier though :D

This is a cool game ! I really like your art and your animations are really clean, the atmosphere is great and i also like the sounds effects ! Maybe you could add a music in the background, and also the possibility to move left and right to make the gameplay less repetitive and more challenging. Despite these points this is a good job, well done ! :)
