Hey!
First of all, great game! The pixel art is very cute, I love it. The level design was well done, nice music, nice SFX (maybe the volume can be a little bit lower though) and you have the theme in there. It was really fun and great experience overall. Really great stuff, congrats on making the game by yourself in one week, you did very well!
I would love to have you playing mine too, if you don't mind of course! ^_^
