So, I agree with what vpeter1119 said. That includes that it is a fun puzzle game. I liked the process of figuring it out. Unfortunately, I had to refresh my browser each time I died. Could be web export being weird, or it could be quitting the game on exit? Might be a speed run feature? Regardless, the idea was good. A little more polish post-jam would be cool. I also think your pixel art ghost fit the style while still looking creepy! Making pixel art unnerving can be hard.
Good job :)
