I say make adds on facebook, twitter, maybe even a TV commercial. Also I think that maybe adds should go on frequently visited game websites such as Kongregate and NewGrounds and possibly Armor-Games.
And I'd say try to get adds on the big anime websites since many people I know via real life or via this game watch(ed) anime.
if I'm not wrong there is UR ad in newgrounds
how about advertise on gamespot and gamefaqs?
how about Cherry credits (for payment) for Indonesia?
if you want to do advertisement on magazine in Indonesia I might suggest, gamestation
example of their magz:
or you could try zigma - omega (most likely omega because zigma is for console and handle game review)
How about Convention centers at the philippines...set up a booth when a some cosplay convention is gonna be held..some thing like that..
opening sms option for philippines would help as philippines are one of the country that cellphone load is widely used..
and make a facebook fanpage and have a daily, weekly and monthly lottery.. (random common cards or clintz for daily, random uncommon or 1k - 2k clintz for weekly and random rare cards or 2k - 5k clintz for monthly and have 10 winners daily, 5 winners weekly and 3 winners monthly or something like that)
internet cafe promos, giveaways (partnering with game sites), and other initiatives..
