I feel like many would point at all of the technology migrations and view it as a cautionary tale: that if you don't stick with whatever stack you picked, then shipping will be a lengthy ordeal due to migrating between various sub-optimal choices all the time. For example, what if someone just picked jQuery for the front end and stuck with that and tried and rewrites or changes after the launch of the MVP?
On the other hand, this no doubt will let you learn a lot of useful things along the way and possibly make you a better developer, or at least give you an idea of which technologies are nice or easy to use, or suited for certain problems.
It's nice to have that sort of separation between the categories of what you aim to do - to study or to try and ship something, because without you see a lot of cases (especially in indie game development, for some reason) where people feel disappointed due to not shipping anything in the end. There's nothing wrong with unfinished projects that let you learn, or shipping sub-optimal code to get it out of the door and start generating value.

Good job, though!
