Try it, if you are having fun that's pretty much all that matters.
Also, don't expect to have the production value of a AAAAA $800,000,000 development team, even if you do use AI. There's only so much one developer can do, no matter how sharp they are. There were tons of awesome single developer and very small team games that came out of the 1980s - so, if you can get happy with 8 bit style you might just surprise yourself.
