1$ is too much
Viewing post in Alien invader :- man on the mars comments
I don't think it's quality enough to charge money for it.
You'll need to make more games, iterate, learn, improve at graphics + code + game design and only then it might actually be worth to sell your stuff to other people. Ask yourself if you would pay for this game with your own money.
This game won't make money anyway, because:
- you "marketed" to 10 y.o. children in comments, who don't have any money anyway
- most people wouldn't play this for free, let alone pay for this
