Love the Zelda 1 stuff going on here. That type of room-to-room dungeon exploring is something I enjoy quite a bit. Something I enjoy less about original TLoZ exploration is the random pushing of blocks in different directions from different sides, hoping for something to happen. The first room in particular could have been improved by making the required push time shorter.
I love how you handled Timmy and the 3 bugs. I didn't see the cheeseburger, I'm guessing that is because I'm just not enough of a hardcore gamer to open up the path to Level 2 hahaha. Excellent art and music as usual!
