Ok, I think I could make the camera angle adjustable.
Yeah I'm working on the problem. But it's difficult to fix without an output log.
You can pick up ranged weapons and I'm working on a new equipment panel at the moment to start a battle with ranged weapons.But I won't add modern weapons, that would fit to the game.The other ideas are really good and I wrote them on my list to choose which I will implement in the new future.
About the problems with deleting units, please answer these questions to help me fixing the bug:
-> After you wanted to delete a unit, will it appear then you press play?
-> Can you select and destroy a single unit?
-> Will the selected unit stay highlighted?
-> Are you using the right key combination? (command + backspace)
-> Can you select the unit you wanted to delete again?
-> Is there a unit which follows the cursor when you are trying to delete a unit?
Thank you for your time!
