Hope it helps you to finish the game
thanks but I couldn't do step 9.I finish step 8, so I have casette and pickaxe, and I touch the tape-player, the casette swap to tape-player and I couldn't touch casette again.
I don't understand which item is swapped next time. so I have pickaxe and tape-player. I start collect items again but finally same wrong swap happened again.
