Wow! Thanks so much for the first impressions! It was hillarious.
Glad you liked it! I agree that more objects should be interact-able.
As for battle, there was actually a brief tutorial when you fight the "tough guy" enemy at the very start. But I agree, it would be good to have that accessible elsewhere.
In short Bravado builds momentum, which lets you use Momentum skills (more offensive), Poise builds Position which let's you use Poise skills (more defensive). Skills can be used as long as you have enough points in either, but have cooldowns.
And yeah, battle is very difficult in the game, but few and far between (Basically all fights are kinda like mini-bosses). It's also possible to bypass every fight.
In any case, really enjoyed your video!
