I loved this and I can't wait for a full version. It has two of my favourite ships, Shadouge and Sonadow, and I it actually made me like Shadamy as well. The art style is great too. It's very cute :]
(One note, though - Sonic's route looks for a sprite called "shadow smirk.png", with a space. Rouge's route, however, tries to access a sprite called "shadowsmirk.png", without a space.)
