Great concept! I liked doing the unique missions at each pentagon - it kept the gameplay fresh and interesting. The style was interesting and there were some fun animations that elevated the experience a lot, like when beating a mission. The tutorial at the beginning was definitely helpful but it took me a second to realize I had to find the matching pentagon color to do the missions. Gameplay-wise it would be nice to have some sort of warning indicator when an enemy was about to shoot. Overall, great job!
