The shield was fun to use especially in combination with the jump ability. However, I could not find a way to play this in fullscreen. This was problematic because I kept tabbing out of the game by accidentally clicking outside of the window. It also appears to me that the game simply shut down after I defeated the boss. This felt a bit unsatisfying.

Furthermore, shooting felt a bit like spam. I think rapid-fire while holding down the left mouse button would have done the job.

I like the way the gameplay is made, I love these shooting games. It seems to me that if you spend more time on the graphics and style, it can turn out something really interesting.
