| Net Revenue: Freeware N/A
Made by the studio Tocoroten and based off of the light novel series Maria-sama ga Mituru, this is one of those occasions where a game is so good that I'm shocked it's 1. freeware and 2. lost to time. You play as Yumi Fukuzawa with angel wings in a tate bullet hell shooting at bats and ghosts and possessed classmates. Normal mode lets you take four hits before death, with each defeated boss, while Child mode gives you 24 hits before death and endless continues at the expense of no score at the end level (and possibly the loss of a True End boss fight). It's really good!

Created during a period of time when tower defense games saturated the market, this entry into the genre is a very special one. You are a volunteer from the besieged world of Dukis to forsake your mortal body and ascend your consciousness into 'pathspace' to fend off invaders from the Bavakh empire - sort of like Ender Wiggen by way of Dr. Manhattan. Along for the ride is an enigmatic, and somewhat bossy, pathspace defender by the name of Aa. As a tower defense, your defensive options take the form of parts of your personality that you literally put onto the path the ships will take to defend your homeworld from harm. As your victories mount, you find your powers growing and your humanity slipping away from you. What are the lives of the people of Dukis, of your own family, worth in the face of the defense of the whole universe? If you've ever wanted a tower defense game that felt like listening to a prog rock album, this is the one for you!
