Nice work, I got stuck at the keycard part but the game is still fun. Love the artstyle and it's just kind of a funny game in general. Thank you for the Portal reference
The game is a little unclear there. Pick up the target's body after you shoot him with E, then use E on the door (when standing right next to it) to progress. Glad you liked the art style and game idea. My love for Portal is still alive, and always will be.
