My biggest complaint so far with the campaign besides the incredibly slow updates is them obviously nit-picking now due to the surge of attention it has gotten compared to what they initially expected.
Those backstarter achievements are so clearly inflated now compared to what they should have been due to backlogged updates. Next we have every single stretch goal update always conveniently needing more funding then the project currently has despite hours and hours of no updates all the while having massive funding occuring between them. That's not even considering the fact that some of those goals are so absurd and half-assed compared to previous implementations and the cost it's asking.
You're telling me cheat codes are more complicated and expensive then a second playable character? Extra bosses and/or enemies in a project where we don't even know the exact number they're shooting for in the first place?
It's garbage and a very poor way to motivate people let alone keep up the momentum long-term.
