A pretty neat little puzzle game, and I liked that it told me my score at the end! I appreciate that the person and his ghost both are equally important in the tasks that they perform. I also really like that each mechanic is gradually introduced to you so that you understand it before moving on. I probably would've floundered if I hadn't understood that the ghost can turn off spikes in that tutorial level, so good on you for adding it!
Cute visuals, fun puzzles, and I hope to see more games from you in the future! Good work!
