1. Jump is not good. If you press and hold "C", it keeps jumping, and I died too many times with this issue. Not accurate controls. One press should be one jump.
2. Suddenly, I fall and die. It is not visible properly. You need to improve the readability.
3. The game concept is good, and the levels are also good.
4. Art Style is also good. But need to improve the readability of the things you want to show.
