you can use keyboard and mouse. I'm still testing it with smartphone too (tapping).

🤔Actually
The new game now implements interactive tickling scenes, and it's needed to touch or click over some specific hotspots to progress on these.
Therefore, working both with mouse and keyboard, or specially using mouse or tapping with a touch screen is recommended.
While the keyboard requirement is to handle the action gauge events which shows a gauge bar to process some specific action in the scene.
