Still reading, but had to share my thoughts so far. This looks awesome! I love the idea of a Martian version of Mad King Ludwig building his own replica of Versailles, kind of a Marzenchiemsee.
The mines being on such a generous timer seems like it could largely make them a non-issue. Perhaps they could be fused so that the player needs to dart through in a straight line to avoid taking damage. As opposed to circle-strafing through it in the heat of the moment, having lost situational awareness. On the flip side, I like the possibilities they create for luring pursing enemies into their own minefield.
And the plasma charge being unlocked after the final mission, or perhaps even for the final mission, seems cool. Maybe once you've used it, your mech is inoperable for a few moments. Like the Death Blossom that leaves the Gunstar and its crew at the mercy of any surviving enemies, or open to a ramming attack, unless they can revive it in the nick of time for a quick escape.
Thanks for the updates! It's exciting to see this already great game continuing to evolve.
Edit: I just reached the bonus section on the MICLIC. And my jaw is on the floor. Wow, this looks cool!
