Thanks for your comment! I initially want to make a game in which when a player controls the character, the character will gradually lose his own power; conversely, when a player leaves the keyboard, the character will gradually gain the power but will move randomly and put himself in danger, and therefore players need to find the balance between control and out of control. I even came up with the name, "Out of Control While within Control”. Even though this idea definitely fits the theme, I have encountered a lot of bug issues since I chose an inappropriate game engine and it's impossible to fix all of them within two days. So I decided to focus on level design only and fit the theme from the storytelling aspect. I know it's too risky to fit a theme in that way since a lot of people tell me they didn't feel the connection between this game and the theme. But anyway, at least I know I should move to another game engine so that next time I can make a game while fitting the theme in the gameplay aspect. By the way, your game is quite interesting, I had a lot of fun with it :)
