多去开妈妈的门
I tried to pick doors with a level 1 including my sister and mom's room. I still can't level up my skills. Maybe just have to wait for the new version of the game. （23.1）
经验值满了之后要到自己房间的电脑上玩拼图才能升级技能
After the experience is full, you have to go to the computer in your room to do puzzles to upgrade your skills
Yes, you're right.
I've fixed the problem. I keep using the keyboard's spacebar to open the door and it's a mistake. When I open the door with the mouse, I can level up😊
