I just found an amazing game through my friend. Absolutely adorable, it’s a Touhou roguelike. Each run is around 30 mins.
Great music, cute art style, really challenging bullet hell gameplay. Some of these fights hurt my brain haha.
4 difficulties, I just beat a run to end the night with my friend on Hard (3rd diff). 4th difficulty, Lunar, reduces max HP and adds new moves to every enemy. The difficulty curving is legit.
It even has co-op. Highly recommend. Here are some of the cuties you get to play as, and so many more are unlockable.
Steel yourself!
