Man, this game is awesome! The pixel art is pretty well done and I really liked the expressions of those ghosts haha! The gameplay is pretty good. Very responsive and everything feels nice. The level transitions are very beautiful.
The only only thing I didn't like was the last 2 levels. Having to go back to get each ghost (or pair of ghosts) made it feel really repetitive. So I died a lot for losing patience and running straight in a ghost.
All in all, a really solid game. Well done!
