Midnight Survivor

"Midnight Survivor" is a roguelike shoot 'em up game where you strategicly eliminate enemies and avoid being cornered to last long enough to face and kill the vampire princess. Levelling up is achieved through collecting gemstones from fallen enemies, which can be used to upgrade skills, passive skills, charisma, and physical features. Every 10 minutes, a boss appears and must be defeated within the time limit to avoid the blood moon, which makes them stronger.
