It looks like the sound options (music volume, SFX volume) are not kept once the game exists. Reproduced all the time on my phone.
Steps to reproduce:
- start game, Options, change 'music' option
- Back (on the screen)
- Back (on the phone keyboard), game exits
- Start game, Options, music option is back to default
Tech details: MB630, OS 2.3.4, APK build Cogs-png-pvr-humble-1332298289_b5007d94104e5b64 (same issue with previous APK, btw).
Thanks a lot for the port, works perfectly otherwise!!
