Well, you have some really good points and I would concede if wasn't for the fact that it took them like 2 years to finish act 1. If we are still on the early stages of development like you say it means there must be something really wrong with the leadership that can't seem to focus long enough to deliver on a timely manner. Need I remind you of the roadmap they released a while ago?I'm not so sure that I agree with this. Except for the part where priorities are kind of weird. Let me elaborate:
Level editing and back end overhauls have already been an early priority since the original version of Beat Banger was out. The game's initial wave of interest included a burgeoning modding community that went out of its own way to develop and use external tools because the game didn't already offer what was needed. Wanting to actually offer support for what said base, the already existing base, makes a lot of sense as a priority. So what we're kind of looking at here is that the first volume was developed while the back end and these features were being developed, revised, etc. That acts as a proof of concept for what the game is going to be, and it also opens an opportunity to actually start monetizing and merchandising on wholly original work instead of the original version of the game, which used borrowed characters. All of that works out, and there aren't any clear issues with doing it that way. This is the early part of the game's development cycle where building and refining those foundations is key. Content updates are slower in comparison because they take less priority than making sure the game works the way that it's supposed to and its features are readily accessible and effective for what its base wants.
But then you've got stuff like spending time programming in and having assets done for holidays, which is comparatively frivolous and can (and should) absolutely wait to be added in later. The only excuse I could imagine for doing this is "we were waiting for certain things to get done within the team, so we just pivoted to doing something small and easy while waiting for completion." But even if that turns out to have been the case, it doesn't feel good to your waiting audience to see little baubles like this that not only get implemented, but then have to be updated and tweaked across multiple consecutive updates where there are no major content changes.
Just to clarify I'm not trying to be an asshole that criticizes just for the sake of it. In my opinion it seems that a lot of people give bunfun games a lot of leeway and not enough criticism for taking so long and delivering so little.
