I'm a long time MMF user who just discovered Construct and I think I've fallen in love.
First thing I've done is build a game prototype for a horror/suspense style game focusing on limited visibility. Thanks to Shadow Casters this was surprisingly easy. Took a bunch of tweaks to get the shadows to behave how I wanted, but I think it works now. Hopefully I'll expand this into a proper game.
Aim the flashlight with the mouse. Move either by clicking or by using the arrow keys.
EDIT: Newer version with combat is below. Left click moves/shoots depending on whether your gun is drawn. Right click draws/holsters gun. Holster the gun to reload. Press space to spawn a monster.
