I really liked the freezing effects around the edges of the screen and the parallax scrolling in the background. I especially enjoyed the tricky situation at the end, where you have to jump across from the pillar. I actually fell there once! =D
Overall, I think this game has the potential to grow into something much bigger if it's expanded and built upon. There's a solid foundation here to work with.
Great job! Keep it up! ❤️
