Im 4 hours into the game and stuck at 2300 AD (I think

at the last factory with Robo and Lucca
and Im dying to browse a walkthrough like I used to when I was younger but I dont wanna ruin the genuine fun of the game
but then Im like Ill just do it for this part thats it, but that makes me think. if its so early and Im just gonna do it ONCE now what makes me think I wont want to again later on.
so Im tryna figure this out cause I know Ill get the most out of it that way. cause I dont REALLY wanna look at a walkthrough, I want to just figure it out, and I can achieve that need regardless if I use one or not, so to kill two birds with one stone (Being playing with no walktrhough and figuring it out regardless) Im trying not to ruin it
