Since I create educational projects (luckily, Quantum Game with Photons http://quantumgame.io/ was partially supported by an outreach grant; all other writings and stuff - not so much), I would love to see some way to support such endeavors.
Also I looked at your game and I really love it. It is so much fun (even though I don't know much about quantum physics). Now just imagine if we have a traditional college-level subject, such as quantum physics, and then use tools like your game to help people learn better. You still learn all the usual topics but the overall learning experience is made SIGNIFICANTLY better by having these extra tools to use to learn. Your game is an educational game but using the same technology used to create that game could also be used to create all sorts of things - experiment simulation, interactive graphics etc.
I wouldn't say there is no innovation though. There are science-based games (https://github.com/stared/science-based-games-list; it was here some time ago: https://news.ycombinator.com/item?id=14661813). I started collecting interactive machine learning, stats and maths: http://p.migdal.pl/interactive-machine-learning-list/ (a lot of things; of course, Immersive Linear Algebra is there). Most of these projects are side projects, though.
Also - I had a plan to extend the quantum game (it is nice to hear you enjoyed it!) to more particles... and then, a full course, with experimental widgets (e.g. showing interference, then explaining it, then giving space to play with it). With some framework (maybe $, but I care even more for collaborators and deadlines), I would love to continue that.
What are your projects?
You can even see it for yourself. This guy started this project 3 years ago. Fast forward to today we can see that his youtube channel has 500 subscribers and most of his videos have around 1k views...this is after 2-3 years of each video being uploaded. Basically, no one is using this site. It is no surprise that we see so many of these education type projects being half built. The developers eventually toss in the towel.
Personally I think we need a combination of both to really change education though - open educational resources and the associated tools to learn the subject better. Preferably free but also low cost might work or supported by donations.
Right now the big publishers pretty much control the entire market. They own the content and they create the tools. Then they spoon feed it to university faculty (by making tools to basically "drag and drop" the content for teachers) and the student/taxpayers ends up footing the bill for it.
