Great art style, and the story is really fun to see come together as you go through. The controls feel a bit too... tight? If that makes sense, like you don't have much room to aim yourself when you jump. It makes platforming A Teeny Bit Frustrating.
THIS. THIS MF right on the top left platform (stage 3). I wait, and wait, and wait for him to turn around, but even when his back is facing me, he turns in split second and our inky friend is dead. Wait, go for it, wash rinse repeat. It's not fun. The timing is a bit too small a window I feel. ;-;
Edit: I figured it out and feel STUPID.
