I will most certainly play your mod soon, once I find some more time to play. Your features are insightful and innovative; the explosions on land is exactly the out-of-the-box style thinking needed to push Mods to the next level. I once thought of Trees exploding, either via some detonation via an interaction.
The possibilities seem almost countless; terrains that give temporary buffs/de-buffs when in their radius, “exchanging” 3 types of a normal unit for 1 hero unit of that same type, water currents pushing ships should they not be actively moving against it.
I sincerely look forward to your developments and hope to see this shared or mentioned in the Reddit or Discords too!
