Cute game, nice music and sound effects. I would have prefered smaller hitboxes but moving aliens. Good job.

This game can be very frustrating at times. The hitboxes for the aliens and holes, especially the holes, seem much too large. I feel like many times when I felt safe, I was thrown into the abyss. The friction in this game could also be higher because you will almost endlessly drift until you hit a wall or move in another direction. This game is hard and many of my complaints probably stem from my rage of dying so much. I would like having extra lives at each checkpoint so that I don't feel like I lost so many lives at one point and could never recover. Other than that, the pixel art is great, the music is amazing, and I love the sound effects when I hit the instruments. I also loved the idea of aliens and of a hedgehog main character. This game is a cute, short, adventure. Well done. 

I almost forgot: I can't see how the game is related to the theme. Maybe you can explain it to me?
