I have found a bug!
If Chiro begins masturbating while standing on spikes or in range of the red orb shooter, and her HP reaches zero before the masturbation is complete, the "View CG" button appears in the game over menu. Clicking "View CG" causes the screen to turn completely black. No inputs will be accepted by the game at this time. On PC, you can escape this without closing the game by Alt+Tabbing out, then back in. The screen will still be black, but wiggling the mouse around causes a button sound effect to play in certain spots. Clicking this invisible button takes the player back to the title screen.

Lol. My dad would always have me help him bugfix his programs because I have a habit of finding niche bugs that are not obvious, but sometimes they can ruin everything.
Once, he was making a slots game, and I was able to break the menu to allow me to bet negative money, meaning losing actually generated cash.
