I love this game as a whole, starting from the background art and the simplicity of how the player and different enemies look. I felt like I gotten far at wave 5 with a high score of 3160 on my first playthrough. The later levels feel like they're really impossible to complete but it was still really fun to play. Although, I feel like a lot of times I did get hit but I never lost health until later on in the waves. The soundtrack is really nice too. This game definitely fits the theme of instability with all the creative bullet patterns of certain enemies. Just great work overall.
