Felix The Reaper vs Feynman rules

Felix The Reaper is a 3D puzzle game. A tight Sokoban-style experience cranked up to 11 in terms of character, color, and dark comedy. Felix works for the Ministry of Death. They oversee all transfers to the afterlife. Hence, making sure people die according to plans and regulations is your primary objective. Make sure people die the way they are supposed to!

Move the sun and other things around to create new shadows to maneuver the puzzle of each map. 3. MAKE HUMANS DIE. Advance the point-and-click plots of each map to set up the death of a designated human at the end of the chapters.
