The Tower of Beatrice

• Zoom in on the red 'M' and open the middle of the gear where the red 'M' is. Take Hamster Bone 1/7.
• Zoom in onto the top of the cupboard to the right. Take Hamster Bone 2/7.
• Zoom in to the bit of floor with a hole to the left of the cupboard, and take Hamster Bone 3/7.
• Zoom under the table to the left with all the green bottles. Take Wine and Gear 1/5.
• Zoom in to the tabletop above the green bottles, and take Gear 2/5 and Snuff/Tobacco.
• Zoom in to the barrel on the left wall. Take Gear 3/5 from the top wall, and Hamster Bone 4/7.
• Zoom into the barrel leaking a black substance on the right wall. Turn the tap, and use the empty green bottle (not the Wine Bottle) on the black substance to get Bottle of Poison.
• Zoom into the left barrel and use the Bottle of Poison on the plant with teeth.
• Turn the tap that the plant with teeth was on, and then use the now-empty green bottle on the white substance to get Bottle of Life Water.
• Activate the hovering statue on the left.
• Zoom into the large board with shapes on it, which is in the middle of the floor. Set the code to 9554.
• Take Hamster Bone 5/7.
• Zoom into the top of the right cupboard, and place the Snuff/Tobacco in the gear-shaped 'hob' on top of it, then press the button with a flame. Take the Cooked Tobacco.
• Zoom into the top left barrel, and use the Cooked Tobacco on the bottom rock-creatue. He will spit out the statue's head. Take the Key.
• Take the Statue Head from the middle of the floor.
• Zoom in on the door, and open it with the Key. Take the Icicle. Make note of the numbers, 5-3-11-1.
• Zoom in onto the right cupboard at the door handles, and you'll see a combination lock.
• Rotate clockwise (the left option) to 5 o'clock.
• Rotate anti-clockwise (the right option) to 3 o'clock.
• Rotate clockwise (the left option) to 11 o'clock.
• Rotate anti-clockwise (the right option) to 1 o'clock.
• Open the doors.
• Take Hamster Bone 6/7.
Note: The game will say that you've collected 7, but you only have 6. I believe this is a mistake from the original Russian translation. Ignore the statement about having all the bones for now.
• Take the Spiritu Ardoris Label from the back wall between the two demons. Also take Gear 4/5.
• Give the Icicle to the snow demon, and he'll give you a Carrot.
• Back out from under the cupboard with the demons, and place the Statue Head where you placed the Snuff/Tobacco earlier. Press the flame button to see it doesn't work.
• Talk to the fire demon in the cupboard twice.
• Give the fire demon the wine. He will decline it.
• Zoom in to the green bottles, and place the Spiritu Ardoris Label onto the brown bottle. Use the wine on the newly-labeled brown bottle. Attempt to take Hamster Bone 7/7. You won't be able to.
• Give labeled brown bottle to fire demon.
• Use the fire button on top of the cupboard, and once the statue head is melted down, use the snowflake button. It'll cool. Take the Holeless Gear.
• Zoom in to where the black poison has made a hole in the floor, and place the Holeless Gear there. When the black poison has done its work, take Gear 5/5.
• Zoom into the middle of the floor where you put in the 9554 code and use the five gears on the slot. You'll need to arrange the gears as follows, from top left to bottom right; Largest, smallest, brown, green, silver. Doing so will set the clock's chains in motion.
• Zoom under the desk with green bottles, and talk to the creature in the hole until he gives you something that looks like Sweetcorn, and take it.
• Use the sweetcorn on the hob (by using the flame button), and take the Popcorn.
• Give the popcorn to the creature, and talk to him afterwards. He'll give you Hamster Bone 7/7 (the skull).
• Put all seven hamster bones in the red-cushioned box on top of the table.
• You should have two remaining items in your inventory; the frozen carrot and the Bottle of Life Water. Put both into your cauldron.
• Look at the hole in the floor. You'll notice a single kernel of popcorn there. Pick up the Popcorn Kernel, and put it into your cauldron.
• Use your empty bottle on the cauldron to get the Potion of Life.
• Use the Potion of Life on the hamster's skeleton. Take the moving skeleton and put it in the hamster wheel behind the red 'M'. You can then leave.
