A more comprehensive list of warnings for Exquisite Cadavre. Keep in mind this is a very short bitsy game, so this list will spoil basically everything: 

• body horror and gore: autopsy-like actions on a corpse, visuals of organs and blood
• Use of blades and needles on above
• implied physical abuse between spouses (but doesn't actually happen)
• animal death (which is quickly reversed)
• off-screen suicide
• flashing graphics: present in the ribcage scene, when moving the cursor upwards
• As stated on the game page, there are no explicit jumpscares in the game. However, due to the nature of bitsy, it does jump between scenes instantly for most game-screens.
