I think you should be really proud of your first jam entry. It's impressive enough to make deadline, but you got a game in! That's awesome. And it's pretty fun, if not super intuitive. I had to read your description through and review the comments here for how to interact with the stones, but once I did, I had a good time with what you put together. I'm sure there's a dozen more things you'd like to do with it (just like I have a whole list of changes for my entry), but don't sweat it. These things are all about improving and being part of the community and you're doing great there.
Excellent solo dev entry. Great job.
