Sigh... stuck in Somber Echoes? Any unlikely help out there?
edit2: Solution is the very tall room in The Grove with several yellow walls along the ceiling. If you shoot off the wall in lightstream form DIRECTLY into another wall, it doesn't cost another charge. Using two lantern charges you can get above the room to find another power up which will open some ways forward. Interestingly, it appears this random streamer I watch play metroidvanias or soulslikes sometimes also hit the same road block and had quit the game for a while until people helped him find the way forward and he picked up the game again. The video in question, should anyone else need better directions / see it on a map or whatever. Thanks 1000% dondashall for the help!
Here is the full map of my exploration, sorry for the garbage quality but to get it all in one shot you have to zoom out all the way and there are no in-between steps, so I just snapped a print screen when it was halfway done zooming out so this is the best quality I could get on it.
I have the second lantern charge, lightstream, but not yet found the supernova or the like, spear through door ability I think I heard about? I have gone over every edge of the map a few times I swear but can't find any way forward. Is there a trick to destroying the security heads so I can travel through their little passage-ways or whatever?
How do I get to the north-westish area that is obviously unexplored? That should be a good start. Thanks. Was really enjoying the game overall but boy this sure killed all the momentum. I don't think there was a teleporter or train I went past that I didn't also use... Bah... Thanks in advance.
edit: Other more zoomed in pictures covering most of the map I think except the part I can't get to;
