Played it for a few hours yesterday and the potential is definitly there.
First thing that comes to mind is to expand the soundtrack. The current music loop gets repetitive pretty quick so increasing lenght and variation might be in order.
The mechanics are there and it already seems pretty balanced at this stage so just keep it up I'd say.
I saw you getting some heat on reddit for using AI but I wouldn't let it get to you, you've got enough work as it is as an indie dev and you're not always in a position that you can hire artists.
Keep up the good work!
