Nice game! Liked it! Quite challenging, indeed. For some levels I had to think what path I should take.
If I could give you two small feedbacks: The level above made me like just a little bit stressed, because I kept dying when thinking by the moving object. I would personally make the spawn a "safe place". Just so that overthinkers like me do not die 4 times before even starting the level.
Secondly, I had a hard time seeing the spikes, especially in the beginning where I just ran into it because I thought they were trees (but that can just be me). Maybe a different colour would help?
But honestly, the sprite for the character! I love him! Nicely done!
