What really impressed me was the original sound effects & OST. For an independent developer, they sounded neither low-quality/homemade nor your typical stock sound effects. That, in addition to its gore-based fashion & charming protagonist, makes a game worth trying out.
In terms of improvement, the velocity of the character is a bit too unnatural for me. It would be nice to add some sort of power-ups on top of the platforms that speed up my movement speed, as the game becomes faster with time. Losing is also a bit unnatural, as I just go back to the main menu. Lastly, a scoreboard of my greatest plays would be ideal.
