how do I level up? I'm on mobile and on the web version. I've defeated at least ten soldiers and the trainer multiple times but I'm stuck at level one.
In .28 you level up automatically and are given skill points that you can spend on skills in the party menu which can be found in the top left.
To avoid balancing issues between updates, you can only level up once atm to avoid early balancing issues, so you've probably already leveled up and have the skill points to spend on skills.
