Thanks for playing and giving feedback! Level ups are for your individual characters, the name of the character leveling up should be visible on the level-up screen, but if you didn't notice it probably is not as prominent as it should be. Based on both your and elb.dev's feedback it seems like I need to give players a few more turns to reach the ally unit before he dies, since both of you gameover'd from his death. The intention was to force players to play a little more aggressively by having a ticking time bomb in the middle of the map that they have to reach in time but it seems like I'm not giving players enough time to react. Thanks again for the feedback it's very helpful!
