Thank you very much for you feedback!
I'm planning to update this little game after the jam with more units, structures and some AI, even though I'd like to keep it open source so people can eventually use it as a base and don't push it too much as a personal game.
Yeah I know that controlling more units is a little bit tricky since you can just select and deselect them, but can't use their skills. I could just add some little buttons under each unit in the "multiple selection tab", but maybe the current UI isn't just the best.
I was not sure about the last bug, since I encountered only one time when I tested the game, but you gave me the confirmation of this, thanks.
I'm going to add these issues in the game page.
