Look, just building a pinball, at all, is a ton of work. You don't have to buy it, I'm not in the least interested in this title myself, but I applaud the effort. Good job shipping even a single game. It's more than some companies have managed!
I'll be honest, nothing here looks particularly interesting to me. It's like a game that got built because it could be, not because someone was particularly inspired by anything. There are a lot of pins already, I kinda feel like if you're gonna do all that work you should at least try something new somewhere. But hey, I didn't put in the sweat and they did, so who the hell am I to say how they should do it?
In 2019 my opinion is if you want to get people excited you need to have at the very least a gimmick, if not an entirely different approach. Getting some good art is cool, but if the physical game doesn't have a toy or something to make you want to hit start then you're gonna struggle to get people's attention now. I think you're seeing that with the somewhat tepid response this game has generated. Maybe the code and media package will turn it around.
I say good luck. It's good to be honest, criticism is fair, but I don't see any point in not wishing them well too.
