Well it seems like an interesting concept and I've gotta say that the base movement seems interesting and has some promise. The attacks could be better but mostly just because there's not much feedback and no knockback leading to a feeling of not a lot of weight behind the swings.
Otherwise though the only glaring annoyance for me would be the area between the start and the end. The fact that it completely changed the view and movement system was a bit jarring and it felt a little slow in comparison to the area before.
It definitely sounds like an interesting concept behind the game though, kinda sad about scope creep. Though it seems that may also be down to the time spent on visuals ?
