Cool story, I really liked the puzzle in the first room! The second one was a bit lame since you only needed the red letters. Sadly we could not figure out the third. (Edit: We figured it out now! I think it would have been cooler if you needed to read more than the red texts)
Tip: When making a pixel-art game, you should not scale the sprite since the pixels will then have different sizes. In general that will not look good.
