Yukkuri Panic: Escalation

Yukkuri Panic: Escalation is an adult arcade-style game similar to Gals Panic. The player uses their cursor to draw shapes over areas to capture areas while avoiding enemies. Each level takes place on top of images depicting alternate versions of sexual scenes from the visual novel Escalation: Kyōai no Fugue. Capturing an area reveals the part of the image beneath it. The game contains a story in the form of visual novel-esque segments between stages which show how the novel's protagonist, Rie Komatsuzaki, is seduced by her lesbian classmates Naomi and Midori.

Levels can contain bosses as well as smaller enemies. The more areas are captured at once, the more damage is done to that stage's boss, and smaller enemies can be neutralized by trapping them in a captured area. There are also several types of power-ups which can be collected to aid the player. The game contains 7 stages, each having 3 levels for a total of 21 levels in the game overall. It also features full voice acting, a CG gallery, and the option to revisit specific scenes.
