Probably because you have some problems with your computer. For us it works in 1 click.

When the MC or enemies execute an attack, the hit moves the character back and forth. For some reason, the character will only move like a millimeter and will only continue to move with a click (the click does not have to be the hourglass, it can be anywhere). It is making combat really tedious. It does not do it anywhere else in the game, and no other game (itch.io VN or steam game) does this. Just wanted to put this out there in case others are having a similar issue.
