This was really fun! The first time I played it I didn't realize you could just hold down the button to shoot so it was pretty challenging. I really liked the art style inn the game and overall the game was very fun and enjoyable :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
