Bugs: The level just randomly restarts. I don't know if this was intentional and there is some type of invisible score board or health bar?
Strengths: I like the visuals such as the character and knife sprites. Very stylised.
Weaknesses: Quite bland backgrounds make the levels feel empty.
Changes: Could add some background art to the level to support the artwork already present. Also make it obvious why the level is just randomly resetting.
