We used to maintain a walkthrough in the very early versions of the game, but keeping it properly updated with the game's environments occasionally shifting added a lot of work to every major update, so we stopped doing it a long time ago. I intend to add a feature where talking to Rodriguez has him give you a direction/hint as to where to go next, but beyond that I don't intend on keeping any sort of official walkthrough
It sounds like you're still at the very beginning of the game, so I'd advise listening to dialogue with NPCs (they often give big or small hints on where to go next), and using the map to explore - if you look at your map, you can see chunks of rooms you haven't filled in yet, as well as doors that you haven't gone through yet, and going to those rooms and checking them out is usually a pretty good place to start when you're stuck
I'm pretty ocd with revealing every possible area of maps. Kinda annoyed me a bit that I couldn't reveal a portion of the dark tunnel with crystals leading to an alraune in a massive room. tried going down that same tunnel and to the right instead of left but I was blocked off by some vine/ivy? If I showed you my current map, do you think you would be able to give any advice? Rodriguez doesn't tell me anything useful, he only keeps thanking me for bringing the doc back and after the worm incident, the doc hasn't had anything to tell me except some CG options.
You're not supposed to be able to reveal every possible area of the map the first time you go there; it's a Metroidvania, you often need to come back later with more upgrades to be able to fully explore.
It sounds like you've reached the Summit already, if you've unlocked the ability to view CGs; you need to explore more there and find some upgrades. If you really want explicit information on where to go, then starting from the beginning of the Summit: you need to head through the indoors area after the platforms at the beginning of the Summit, then once you come out of the other end of that building, head upward as far as possible (which requires going through a building, heading right, and dropping down onto an area just above an save point), then follow the path until you get the Wire Shot upgrade. Then use the Wire Shot to explore further.
Like I mentioned before, it's helpful to check your map and see where you didn't finish a room or go through a door - while it's true that often you can't fill them in without future upgrades, the correct path will always be in one of those spots. None of the critical paths in Crisis Point are "hidden" in the way certain metroidvanias hide them, so the map is an invaluable tool for finding your way forward.
You can also leave custom map notes on each square of the map, so in cases like the one you're talking about where vines/ivy are blocking the path, you can leave a note there saying "vine/ivy blocking the exit" or something to that effect, so you can easily remember what was there later on without having to actually go there
I thought about doing the notes thing but I wasn't sure how useful it'd actually be until you pointed out a really good use for it. I'll try that and see if I can make more progress from here on. Thanks!
