Complete effects guide for I Had The Strangest Dream, Ivan (Version 0.00).
Alexei's Effects
Traveller
Enter the Nexus. Go left (or right) and interact with the hat on the ground.
Surfboard
Enter the boat traincar. Take the north-west path then go north where you should come across a pipe going round in a clockwise spiral. Go into the pipe. Go through the pipe to the other side. You'll arrive at an island with a polar bear and some trees on it. Interact with the surfboard.
Cowbell
Enter the burger traincar. Go south past the restuarant and enter the double doors in front of an "Employees Only" mat. Head down to the oil pool then go either left or right. Where the path splits, go down to where the meat grinders are. Flip the switch to turn off the meat grinders and a cow will run offscreen to the right. Go right and interact with the cowbell on the ground.
Burning Man
Enter the castle traincar. Follow the hall south until you reach the balcony, then go left. Enter the room to the north at the end and take the stairs down to a dungeon. Enter the door at the end of the path and interact with the flaming man through the bars.
Power Amulet
Enter the day/night traincar. Move to the world's underside and follow it left or right until you reach the Easter Island statues. Interact with the path between them to travel to a jungle. Partway through the jungle, you will see an explorer. Follow the explorer through the subsequent maze. When you reach the end, a short scene will play; to avoid the statues take the small path on the left, then interact with the amulet on the altar. (You will need to use it shortly.)
