I like music and graphics but the enemies do the nothing. You should to add more fun staff.

 It's a cool take on Doom. A bit confused as to if I was making any progress, I think I kept walking in circles. Either way great work! Keep it up! 

Great job! Colors gameboy a like great touch!

Finished it! You definitely nailed the gameboy feel.

For constructive criticism: It took me a while to figure out what I was supposed to do. I also don't think the enemies did anything. I think something indicating that you need to click on the edges of the screen to advance would already be very helpful.

Cool - Well done
