I got stuck in the blue keycard well of water. I think there might be several linedefs which lower the rings further down if the player walks across them. The floor got so low that the only jumping would allow me to escape.

Yeah, it was intended that the well kills you if you go into it before you activate all four switches, so I didn't bother making a way to escape. Don't know if that is good game design though. Should I change that and maybe add a way to get out?

Maybe a warning in game somehow/somewhere not to go into the well until you have flipped the switches?
It's not good game design if you end up in the well and die, but don't know why. If you know why, then it's fair enough. How to let people know why is over to you.

Re: Polar Excursion - A heart of cold [UDMF]
I just played your map a while ago, and it's got some great points, and a few troubles.
First off, love the general design, from the train that has a snowed under locomotive, from the vast main area with the various teleportation switches to "climb" back up, to the train station where the final showdown is.
Second would be about the soft lock you have at the end: if you click on the wall barring the final showdown without clicking on the sos computer, that final wall meant to go down after the fight is stuck and you can't exit. I would recommend the second to last wall barring entrance to the arena is also controlled by the yellow key computer, or the yellow switch brings up another switch near or in front of the wall for the player to click.
Next up *Spoiler*

Spoiler:Other then that fight, I did like the map quite a lot and I love the custom work put into it's textures and some decor, very cool work!

Re: Polar Excursion - A heart of cold [UDMF]
Thanks for the feedback, it is much appreciated. Yeah, I totally forgot that you can access the final fight even without pressing the "SOS" button. I will definitely tend to that in the future update. Good point about the invisible archvile, it was more meant as a joke to see how people would react to it
, but I see how it doesn't actually enhance the experience in any way so I will change that fight also. Thanks again.
