Is there any stats I should focus on and make an impact right now in the game? I know you lose intelligence if you go for gloryhole scene. Is intelligence important at some point right now and possibly any other stats like cardio, strength, etc. that make a difference and change a scene, trying to figure out which free roams I should do and to not miss anything right now
Most stats do not seem to matter. They are more a mirror of your decisions than a requirement for specific options.
Example :
In other games (and in real world) you need some strength to lift a weight, eg if strength >= 2 then ...
In this game you don't need strength to lift a weight but get a small strength increase as reward for the activity.
There is a check in Ep4 :
"Do a barrel roll" if mc_willpower > 8 or mc_strength > 3 or mc_confidence > 8 or mc_stamina > 5
However to see the lewd scenes you want to get caught, so the barrel roll is just a small extra scene.
Best play the game first time as you like and ignore the stats. If there are certain scenes you do not get, it's usually based on decisions (or missing relevant chats on the phone) and not on stats.
