Hi,
this game is pretty good. What makes it better is that it's 1 mb, not using an engine seems to be really useful sometimes. The animations were, although quite simple, fit for the job, just like the art-style (especially knowing you're limited by a color palette of 2 colors). I had to play it 3 times to realize that nothing was going to change, but I was pleased :) As another person suggested, you could always try to expand the game a bit more, like the guy in the room just attacking you, but with the benefit of not needing to worry about size. Being made by one person, I think this project was a success!
Keep up the good work!
