Love the character!!! So cute, and the trail and movement are so nice. Also great job with the tutorial, the light mechanic worked out pretty well for that too :) It was very sad when I hit the spikes... because of the mood of the game could be interesting to try making the sound when you hit the spikes a 'puff' like smoke instead of the shatter, to make it feel less heartbreaking (like the character is a ghost so it just puffed but will come back).
Really liked it, great work.
