I like the idea, and the execution was for the most part quite fun. There were however a couple things that made it harder to enjoy. The paper shader overtop was too opaque making it really difficult sometimes to focus on the visuals that mattered. More importantly however, the camera movement was way too fast, so it became very difficult and frustrating to orient the camera in real time to be able to accurately get the right angles. It also felt like the long curving hallway level should be one earlier since the one just before it was much harder imo.
Lastly, I really appreciated the real quick set of tutorial levels at the start which made it super easy to understand the mechanics.
