Cute art! I love the concept, and I do think that the game is pretty cohesive.
The biggest thing I don't like is the camera system, it's pretty disorienting (there's some good examples online of when to switch and move camera positions, such as a 2/3rds threshold. I also know GDC has some good videos of camerawork as well). I think there are some issues with the platforming. The control scheme is questionable due to the following,
- Lack of coyote time (causes some moments where you feel like you only have one jump)
- Easy to produce wall-sticking.
- If you try to jump/dash/shoot, the animations are buffered so that they don't happen immediately but are chained. This makes the platforming controls really unresponsive to immediate changes and reactions, which are pretty important to the feel of this kind of game.
I do appreciate the pause menu and sliders (the ambience slider is missing which is the loudest sound though). Other than the controls, I think the rest looks very polished.
