Okay, here's the things that stood out when I tried it this afternoon:
Navigating: I honestly couldn't remember Planetfall's layout. Can you make a custom texture of a map or something?
Detail: Every room I saw had no detail. It was also annoying trying to figure out where the button was to open the hangar door. Suggestion: add a console with red lights next to it that opens the hangar's doors.
And make some spinning lights and a klaxon prior to the doors opening.
The underground base: The base with the huge gaping hole as its entrance? Yeah, well, the console to close the door wasn't working, and when I used a cheat to unlock the button, it closed, but then immediately opened again.
Noclip protection? When I tried to noclip out of the underground base mentioned above, it teleported me into one of Planetfall's cells. This was very annoying when I have to noclip all the way back down.
Glass building protection: On the big tower with the glass ramps doing downstairs, add a door to the landing pad and some protection for the big gaping windows. Shields anyone?
Detection on planetside: I don't know how significantly this would impact framerates, but what about some trees or something? V2 has rolling hills, which is an improvement, but it's still extremely easy to see someone on the plains from the guard towers.
That's all I can think of right now, but I might add some more criticism.
There will be textures of the ship, but there's no point making them while I'm still rearranging the layout.
The basics go in first, detail comes later. The basic rule at the moment is that every single room will recieve a lot more work EXCEPT for the main engineering room, but even that will be getting a little.
The door to the tunnels cannot be closed unless the generator is online. At the moment it starts off because the base is meant to be half-collapsing. Also, there's a temporary system in place so that if every player leaves the upper tunnels, the door auto-opens. This is to prevent it becoming 100% sealed off.
I know that anti-noclipping may be annoying to you, but noclipping itself REALLY annoys me, and no, I do not intend to remove it in the final release. All secret areas, blast doors and shields will have anti-noclipping. Basically, when I seal myself in an underground vault with no possible entrance, I want to actually feel safe.
What landing pad on the big tower? If you just mean the roof, that already has a door. I have been planning to add blast doors to the windows, I just haven't got around to it yet.
There are already a few trees on the ground (admittedly very few), but I saw no point in adding trees when I would have to re-position them all every time I changed the landscape.
As for the missing textures, that is Pakrat being silly. If you let me know which textures are missing, I will make a list of ones I will have to add manually.
