I have just bought this game and am not able to drop Soaked Boots (in the tutorial) into the Drop Item circle - it just doesn't register. Also, pressing Delete doesn't work!
To be honest I haven`t played the tutorial in a LONG time . I don`t think it matters as you won`t be overburdened by the end of the tutorial anyway . I would just play on until you get to the point where the game suggests a game difficulty .
