I believe it should be possible to beat whole game on Easy mode with a laptop's touchpad, without swords (in fact Easy mode was optimized for this kind of playthrough originally).
Slowmotion is still quite important to use though. On some of later levels more of a strategic positioning is a way to progress too.
There is a quick saving and quick loading buttons - perhaps these could be helpful sometimes too.
Another thing I've noticed during development - soundtrack/listening to music/talking to someone while playing can affect your in-game skills negatively. Game in itself isn't really hard but it needs more focusing despite looking simple. In a way - it is all about taking control over randomness.
Game was released in early 2010s for the first time, perhaps difficulty feels different for different generations of players.
