Very cool art! It took me to long to realize you could press Escape to open the shop. Although the gameplay itself is a bit primitive it was still fun nonetheless. I got to a score of 850. And also noticed that if you keep clicking on the endscreen the bullets would still get shot and you could keep increasing the score. I also really liked the music.

Would love to see a full game with this sort of art style, very very cool imo!

Looks great, reminds me of undertale
