Just starting

Wanted to play Library of Ruina for a second time this weekend and it got me thinking I wanted to check out Limbus company finally if it is time gated or you need to play it daily I figured I could just jump between both games

I've never played a gaccha game or anything like this before, So I was hoping to just get some tips

I finished chapter 1 just a bit ago and I'm unsure of a few things

What am I supposed to unlock, are their wrong choices for spending resources? should i just keep doing the main story or do I need to do these side activities to lvl up my pages

and if its more of a daily game is their some sort of goal I should attempt to do every day because I have daily objectives or something
