I think the graphics and music were great and very gameboy. I liked the puzzle aspect of trying to get the coins sometimes, and it was fun how each room added new mechanics like the bouncers or the switches. Fun game!

Congrats on finishing your entry! It's a fun little game with some interesting  mechanics. If the collision detection and controls were a bit more polished this would have scored much higher. The keyboard layout is a bit weird for me, WASD + E + SPACE.

The text in the intro is a little hard to read, for the rest it was clear what to fun to play! Perhaps next time you could add a readme document with some details?

Cheers!
