This is so incredibly well done. Everything flows so nicely on the digital side. Nice job!
Here's a suggestion for you. One offs or "boutique" games .... there's a lot of people out there with more money than common sense. Prime example years ago when apps were becoming a big thing on the IPhones, some dude made some stupid app that show cased diamonds. Don't quote me on this but I believe the price for this app was $30K. Paris Hilton and a few others bought it.
IF I were you, I'd finish this up and put it up for sale at $150K. It's literally a one of a kind. If it doesn't sell you're out nothing
