I'd recommend having a way to create a sense of depth perception. Right now, it can be hard to tell if the player is lined up with an obstacle. Overall it seems like it's a good concept.
Im actually going to fix it in a moment, im just exporting the new build, i made some changes to the camera positioning and to ensure that everyone can play it without having the graphics broken.
But thanks for the suggestion, many people have told the same, and im aware of it.
