The banner is beautifully eye-catching, it's what made me want to try out the game!
I wish it wasn't such a carpal tunnel sim and that the game would let me hold LMB to shoot
I wish the weapons had different sprites or had more distinct colors, I was picking up whatever because they all looked the same and there was no time to look at the details.
Music very good! Very climatic, I loved the choirs.
Overall I really liked the pixel art style. It was very original and fit the vibe. Congrats to the pixel artist!
The game was short but solid and could be even more fun if polished and expanded.
Good luck and thanks for making it!
