Nice job on the game! That was a cool light/dark system and I think it was a fun idea. I did get a bit lost though and since dying makes you restart the entire level it was hard to keep replaying it. But good job overall! I would also suggest putting a small game like this on the web vs download. more people will play it if they don't have to download it!

I like the concept, but it needs a little storyline in the game in my opinion.
Also, as bug finding, the "picked up coin" counter doesn't reset when you die and i got stuck in a room right after those blue ghost....
