In regards to using the traps or water to destroy enemies: using the inventory system you can equip different weapons. Your default weapon is the tranquilizer which does hardly any damage to the enemies and puts the wolves to sleep. If you equip a shotgun/grenade/pistol you should find the enemies easier (otherwise you can also run past them in the first level to get to the sensors in The Peaks). Also collecting spanners increases your damage dealt as well as movement speed as part of the "level up". I apologise for neglecting to mention this in the game page instructions section.
