This is by far one of the most polished games I've seen. I absolutely love the artstyle and the boss design is amazing! I also really liked the shop addition I think it makes killing enemies very rewarding. I'm just not to sure how to kill the boss. I've been shooting it like crazy and neither my bullets nor my missiles seem to be doing anything against it. After 3 tries I just gave up, which is a shame cuz I really wanna see the ending. But incredible job nonetheless!
