Hello! I've been playing some Tower Defence lately and I've thought of a small but helpful suggestion.
Please post feedback on this :)
When playing Tower Defence you can upgrade your troops all the way to level 5. I was playing earlier today and we were being attacked with a lot of enemy troops. When sending troops of my own I decided I wanted to upgrade some of them. Whilst doing so, I thought it would be pretty neat if any troops that you could upgrade enchanted themselves so you'd be able to easily tell which troops you can and can't upgrade.Please post feedback on this :)
