On this page of our Tell Me Why Game guide you will find the answer to the question - How to run in Tell Me Why?
If you've played studio's previous games, you've probably already tried running using one of the available buttons. Repeatedly clicking Shift, however, does nothing here. On the contrary, it opens up dialog options.
The characters can run only at certain moments. These are very specific situations. Sometimes running is possible in open spaces. Another time, indoors. You can't influence that. These are the only situations when the character wishes to move faster.
However, you can slow down the character's movement. You do it both when they run and when they walk. It's a great way to explore memories. The characters move quite chaotically, and this makes it is easy to slow them down.
To slow down the character, Press Control (Ctrl).
