A huge thanks for this detailed response and the recordings!
I think what you wrote is 100% valid, the frustration you felt with coordinating units is super important feedback and doesn't come across as nagging to me. You are right that the goal of the game (as it is now) is map traversal and combat is an obstacle along the way so I think that some friction around movement and positioning is necessary for this to work and offer any challange. I just need to find a sweet spot where I don't piss off people too much ;) I may also introduce more varied objectives or change the goal structure completely, I don't rule out any options yet.
Also thanks for some fun ideas there - I will definitely try longer ranged attacks or some abilities that shoot over obstacles. I'd like to experiment with round structure as well but I'd first need to level up enemy AI so they don't get stomped by player coordinating their moves perfectly ;)
I'm glad that despite the frustration and criticism you still found the game fun and even seem quite enthusiastic about it. This quote "hoping that the game gets developed into my next obsession game" made my day!
