I really like this idea! The art is cute and perfect for the style of game, and the concept of using movement to constrain and kill enemies is pretty unique. However, the controls are really difficult to use and hold the game back from reaching its potential. It is almost impossible to move anywhere if you get caught on the edges of the screen. This is fixed with inverted movement, but inverted movement makes it difficult to get off of the top of the screen to transition between levels. I honestly don't know a good solution for this, but it would be worth looking into if you want to rework the game at all after the jam. I would be curious to see how this idea would play out with a more accurate and responsive control scheme.
