While being close to the point of interest player character would walk to get in front of it.

Walking activates automatically. Player doesn't have much control over it. But if during walking player selects a different point of interest, the player creature would start moving towards a new target.

Tapping on the set pointer would increase the speed of walking. Maximum speed depends of the creature's energy capacity. And on the current energy level.

~Spamming the pointer would make the player's creature to teleport to it 😈

Walking doesn't consume energy.
