Indeed the art looks solid enough that it makes me want to try it.

Possible design improvements (all can be seen in the last screenshot):

* the color of the text in the top left corner is uncanny, doesn't blend with the rest of the screen, and doesn't provide good readability.

* huge areas like the right side look too patterny. Using something like procedural generation would make it feel much better (see e.g Tiny Wings)
