It is totally ready for visitors. I visited, I enjoyed it. Doesn’t seem particularly wise to advise people something isn’t ready for people to visit, when those visitors are the only ones who can actually give useful feedback.
One hopes that the author didn't need me, a stranger, to tell them that this site is missing most of the fundamental features of a shell. Feedback is valuable, but strangers aren't going to visit something that clearly doesn't work a second time to see if they're making progress. There is a reason that early testing and feedback on prototypes is limited to in-house or pre-existing customer review. The author is entitled, and even encouraged, to ignore me--but my feedback is that they should have waited until they were closer to their goal and general feedback would be more valuable than hundreds of copies of "it doesn't work".

This is the exact opposite of useful feedback. I hope you realise project that is literally intended for fun...
