I loved the concept and art style. The walkthrough link in another comment helped me with level 2 but I couldn’t beat level 3 yet (will give it another try later).
Something with the controllers tho: I’m pretty sure in my first gameplay it was working with AWSD and space, which is great once we have to use mouse, but on a second game play I couldn’t make it to work and had to use the left, right and up arrow keys which is not that great.
