Sweet! I just love low-res graphics like this (I grew up with a Commodore 64, that might be why). Nice touch with the easter egg too. There are a couple of typos ("grate" instead of "great"), but that's the only "bug" I've encountered.
If you'd like to make something similar with few colours and big pixels, you should totally enter this game jam:
