I liked the pixel art and the music. The whole concept of a game revolving around a favourite saying of someone is nice too. But I missed some instructions what to do. It took me five minutes to figure out that I need to press Space just to enter the next room. Then he keeps talking about tasks - but which tasks are those? And the key in the tree in the park - is there a way to get it? I jumped onto it several times, pressed Space while flying though it and nothing happened :( sorry, that was a bit much criticism. You clearly got you basics right, implemented movement, sound, story, etc :)
If you feel like it, leave me a rating and comment as well :)
