- Edit /data/data/com.rayark.pluto/shared_prefs/com.rayark.pluto.xml
- Change the line that looks like float name="TreeHeight" value="0" to float name="TreeHeight" value="50"
- Play for a while, every time you clear a song, a new one will unlock. The newer songs in Deemo 2.0 are on scrolls in some of the rooms, you have to go find them.
- After you've got all the songs you can edit another line in the xml. float name="Ladder" value="0" to float name="Ladder" value="1.0"
- Now you can go play the end in the Ladder room and unlock the last songs this way.
