The core idea of this project is really excellent! Using the camera as an "attack" against monsters is quite a fun concept, and the style of the game makes it overall a very cozy experience.
As I was playing it, I was thinking that it would be pretty cool if you could hit multiple enemies more easily in the camera crosshairs. That could give some incentive to kite enemies around and group them together to do higher skilled plays. That might require making the overall camera box smaller to balance it, though. Alternatively, maybe getting the monster in the center of the camera could be a critical hit to damage them more, whereas getting them in the box at all still damages them.
Generally, though, the presentation was great and the gameplay idea is really solid. Great work!
