Yellow
Yep! Refining the available colors is high on our priority list.
Block Palettes
Not very final. We haven’t made updates to them in over a year, and I’ve also been vexed by the lack of options and a lot of their visuals. Fully custom ones (outside of, someday, mods) are fairly unlikely since there’s a surprising amount of tech complexity behind them (e.g. getting them to “bleed” into surrounding blocks). I do hope to be able to somehow allow custom color tinting someday, however.
Bracing
These are great thoughts & notes – I think I agree with everything you say here, and have had concerns along similar lines about the brace family of systems. We’ve added additional brace triggers in for the nelson’s armor (so you can brace against grapples) so it might be possible to give the Nap something similar. I’ll make a note to look at it when I finish the NPCs and come back around to polish up the PC systems.
I am actually one of the few Napolean Fans! After my last campaign, despite my best efforts, it became my favorite mech. I documented my journey here. So I’m motivated to help make it as good as it can be in LT.
