BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
Let's be clear, this game isn't balanced, but that's the fun. If you want to make ridiculously overpowered characters, you can. It's going to be grindy, but when the result is power overwhelming, it's worth it.
There's a pretty good story here too, though it's a little confusing at parts and I'm pretty sure it doesn't hold up under scrutiny, but please let me know if there's any JRPG that does...
You're not going to like this if you want fast paced action. Battles are long, drawn out affairs, but that's what you're asking for when you play a tactics game. The battle system isn't as deep as some later fire emblem games, but it's good, and the job system is well done.
If you like tactical JRPGs, absolutely pick this up. If you don't, this won't change your mind. If you don't know, try a demo of some modern fire emblem game perhaps.
