Oh my music O_O
This is not perfect, neither very good. Still it is a working game you made without help of others.
You still need more Sound-effects, maybe more Music, and a pause-menu with options. better Graphics wouldn't be bad. Score to be saved somewhere, somehow. but that might be harder to do as the rest of my recommendations.
I made the music over a year ago... so if you continue this, i might be able to compose something much better... but oh well, even if this has a bad rating it feels too good that my music is used in a flash! =D
