idk if some chapters block you off from backtracking or if i was just too tired that night i was playing to notice little tunnels, but i went back through near the end of the game looking for some last resources for upgrades & all but one of the "dead ends" let me pass through. so just correcting myself lol. Granted, that led to a new issue of not finding backtracking for resources particularly enjoyable. I'd have preferred a resource detective vision or something as the final upgrade over the revive thing that I dont think I ever used.Been enjoying it overall but I realized I forgot to scan a bit of alien tech & Ive found myself annoyed with how little the game lets you backtrack. The fast travel points I tried just lead to dead ends - most of which required me to quit & reload to get out of. Makes me wonder why they even have multiple fasttravel points in the first place if the game doesn't let you actually reexplore areas. The landing sites couldve just been one way trips back & forth justified by the ship's lack of fuel.
fun game imo, as a platformer fan it was pretty much comfort food. Just rock solid with some neat stuff even if it wasnt mindblowing or anything.
