I'm digging the CRT filter, and the little goblin character is super cute! Definitely gives me Zelda vibes, and I'm impressed at how many levels and tilesets you implemented in the time window.
I do think it could use a serious amount of polishing, though--there are a lot of typos, as well as game-breaking issues, like that if you push two statues next to each other it's impossible to complete the puzzle.
