The Map turned out nice but there a quite a few issues that need fixing:
Not all Lava patches seem to work in terms of heating up a mech and the lava rivers that flow from the platform sometimes end um getting you stuck. I'll post a few screenshots.
Also the Minimap in spectator mode sometimes glitches on the map, when switching between allies quickly they are show at different places on the minimap.
Generally, I was hoping for this map to be more over the top. There are so many hot glowing patches of rock and other little things that could also heat up a mech, or at least give them the effect of the crater in Caustic Valley, standing near one increasing the heat by 4-5%.
The Center Platform does not seem to be a hotter place than the rest of the map, why is that ? It is right above a lava lake, at least make the platform a hot zone like the crater in Caustic Valley.
Also the ambient temperature of the map seems a little conservative ? 105-110°C would have been cooler and encouraged more use of mixed weaponry, lasers and PPCs would have a clear disadvantage in this place.
And finally, why did you change the lava damage from internal damage to damage to armor ? I could see that at first external damage would be ok but I would have liked it to turn into internal damage after maybe 20 seconds or so. This would be a major factor when it comes to distributing your ammo in the mech

If you stand too long in that lava lake sniping people with your AC2s from below or throwinh LRMs your legs might just blow up from below you due to ammo explosions because the ammo is getting frekishly hot.
You missed so many opportunities with this map to turn it into something special and new but probably discarded them as too much. While many people would be whining, I am sure of that, this map could have been something exciting that brought some new tactical elements to the meta game.
Also I'd love to see a King of the Hill type gamemode in the future, defending a platform for a certain period of time. Maybe even a team already spawning at the defending position so that it is clear who has which job. The usual two spawpoints spawning the attacking team in 2 locations. You could already do this on Caustic Valley (Crater), Terra Therma (Platform), Alpine Peak (one of the many deserted bases)
The screenshots of the guy I watched being stuck in the lava river will be down below:
