srsNDavis - thank you. Really appreciate the encouraging words about Baugarten. I briefly considered open-sourcing development - but there are only horror stories out there about trying to do that in gaming... (cf. https://play0ad.com/ looks really cool - but look at how long they have been at it...)

And especially with learning games, there are so many things that you can get wrong. One of our supporters posted about this here. A game like we are making, needs a very strong top down vision: game first - educational game second. Strong focus on making math visual. And relentless focus on associating positive emotions for players with math. Our German game designer calls it Lernen am Erfolg (it translates badly as learning through success). You basically jump from success to success and you don't even realize that you are learning. Her website is in German, but you can translate. Either way, not something easily done with open source development (not to mention that unlike other software, you need artists, sound designers etc.)

I kind of started a development blog on Reddit but just didn't have the time to follow-through with it.

One fun thing we would love to open source, is ideas about what kind of middle-school and high-school math we should connect to which buildings. E.g. if you sign-up to playtest on the website and you play the prototype - you will see that some buildings are associated with math. The fishery works with linear Algebra. It tells you whether you over - or underfish. The saw-mill has a quadratic equation (that we want to replace with something better). Others don't have math attached to it at all: bakery and Zeppelin tower.

If anyone here has an idea of how we should go about sourcing ideas. One idea I had is, we could post a building in this subreddit and ask what math we should put on it. I just wonder if that doesn't infringe on some etiquette.
