Day 13: Whoops, fell asleep before posting Day 12 progress last night so I'll do that now.

Main menu, game over screen and victory screen are all done. No pause screen yet but it's on my to do list. Also added a health system so that you can actually die and I get to show you my game over screen.
Now for the Day 13 stuff.

Made my monster. I call him Meatman, he chases you around while covered in smoke to hide the fact that he doesn't animate.
I've also added some gates that require keys, obstacles, a water dripping particle effect, some wall graffiti, actual candy in my game titled "Free Candy" and have begun to add a gun and shooting system for the final showdown.
A pretty productive day in all, just need one or two more things before it's a playable game.
Day 14 Plan: Finish the shooting mechanics and make my final encounter, change the floor materials, add some more spooks and fix some bugs.
Currently my bottom floor has two of these meat men running around freely as they can just phase through the obstacles I stuck in their way, so gotta fix that.
