Other than the awesome art style I've noticed that this game has a ton of variety so it's doubtful the combat will ever get old. Since most areas have a different challenge to complete that is more than just fight stuff.
Like one mission in the forest is actually a stealth mission or in one of the underworld missions it turns into a platformer for a few minutes. Plus I like how each boss gave me a reason to switch up my tactics. Didn't really see anything wrong with the combat but I guess it does take some time to get used to it.
My mom was a elementary school teacher for over 30 years and it can certainly be overwhelming sometimes. But she never gave up on trying to make everyone learn something new before the school year was over. Remember no matter how hard it gets your hard work will pay off one day if that annoying kid turns into a responsible adult.
I've only backed 3 games on Kickstarter and they were all fairly high profile so it's unlikely that they will explode at some point. Mighty Number 9, Shantae 1/2 Genie Hero and Amplitude all seem like they are progressing toward their projected release dates.
