just three hints to help out
1. to get the screwdriver: talk to the bartender TWICE of different dialogues and you use it to get batteries out twice as well as you put batteries twice into two different objects
2. the combo you see from the book for the lock: the numbers doesnt mean the order in which it should be clicked but HOW MANY TIMES you should click that specific spot
3. yes you have to mix two items in the same liquid for later
I had no idea how to unlock the cave door until I read the comments below. Once you finished talking to the professor, game was completed. :/ Why did I have to collect items in the game without using them?
door code isn't working
I literally beat this game in 3 minutes. I just went up the ladder and went into the room with that cave, and started randomly pressing the green buttons and eventually got the code right and won o____o
Good game - didnt get the medal though!
