Yeah we could definitely do some kind of "toggle off" walls. I can at least play with it as that would be cheap to implement (i think :))
A suggestion about loot i heard is to just have the character walk over and automatically pick it up. No dialogs at all. I liked that. Reminded me of Steamworld Heist and feels cleaner.
The main problem with changing action points now is it would require a massive rebalancing. That scares me a lot as this version has been played a lot at this point. I've got Templar BF but haven't played it much yet. I'll check out the other game too and see if there is something to borrow that won't fundamentally change the game.
