You guys do know you can change the voices and text to Japanese in the options menu, right?
If you find the gameplay bland, you're probably not playing it properly.
Gameplay is basically like this : use barrier to collect enemy bullets, destroy enemies before they disappear from the screen, deactivate barrier during moments of little/no enemy activity to recharge barrier, repeat until you reach the first shop, buy all spell cards available at the shop. From then on, use a "barrier -> spell card -> barrier -> repeat" cycle for the rest of the game. Always, try to keep your stock of spell cards full, and if the shops ever have any MP bottles available, be sure to buy them. If possible, try to have at least one spell card available when you enter a boss battle, but don't activate the card until a few seconds before you defeat the boss.
If you still don't like the game, then I guess it's just not for you.
