Oh, thanks! Usually, it will just redirect to the US store, so I assumed it wasn't available.
After playing through the first 12 stages, I'm impressed! This is very much classic Bust-A-Move/Puzzle Bobble. The graphics are tight, bright, and clean, and the music is just as I remembered it (I haven't really played any PB games since the Dreamcast version). There is really nothing new to be had here, it's just a super polished mobile version. You get a daily mission every 8 hours that grants you access to the bonus round where you can win a ton of coins. Coins are won at a steady rate through playing the stages, as well as meeting certain criteria on the map (such as getting 25 stars to unlock a treasure chest, or playing a certain amount of stages), and can be used to purchase power ups before a stage (the only one I have unlocked is the Sniper Sight, but there are a total of 4), as well as a new character. Purchasing characters is very much like any gacha game, except there is no premium currency to use here and there are no IAPs for coins. 30,000 coins will grant you an A-SS (rare) rank character, while 6000 coins will nab you a more common monster. You level up your characters by either spending coins to level them up, or by getting multiples in the gacha machine. You equip a character before a stage to unlock their abilities. Some grant you bonus coins when you clear a stage, while others will grant you bonus points when popping certain colors. There appears to be a great deal of characters to unlock, as well. The other gacha element in the game would be the daily login rewards, but that's it. The game also does NOT require internet to be played!
The game is kind of everything you could want in a Puzzle Bobble game, but I hope they add an endless mode, or extra modes in general, somewhere down the line. I do recommend changing the control scheme from A to B. A-mode is tap and release to shoot a bubble, while B-mode lets you aim by tapping and shooting by tapping the shoot button.
