Nuclues (Demo 2) file

Here are the bugs i found: TRAINING COURSE: right at the start there's a gap in the goo, in the room right after you get the crow there is a pipe prop is clipping trough the wall, some brushes are off grid a bit,you can softlock yourself at the part where you get the gravity gun by destroying the crates, multiple gaps in geometry, also imposible to get to the buggy also try to avoid senseless invisible walls
honestly most of the maps should be merged into one, if you load into the fourth map without and buggy and then return it will no longer be there, the buggy bit is pointless you travel such a short distance and the you gotta leave it behind, in nu_c2m1 the game crashes when you pick up the gravity on the crate and the lighting is broken near the vent, the door in nu_cum3 just doesn't open so i had to noclip also you can just softlock yourself by jumping in the water, the strider fight is too easy, you can just hide behind the cargo and the strider can't do anything, the xen was a bit fun but there were no nodes so the ai was disabled
TLDR: honestly for a first mod this was okay, but i think instead of trying to make a mod, try to improve your mapping skills,having your first mapping project be a whole mod is too chanlenging, i had some fun, but there's a lot to improve

When I want to take (in the beginning) the gravitygun - or even when I just touch it: the map crashes. (several times)
And giving myself by cheats the gravitygun: doesn't work... :(
(although I used the right command)
