### 5/5 — I wish the other whales and dolphins are obtainable

*2025-11-07*

After the game had updated after the problem that had been happening from not being able to load up, I really am having fun with the game! I managed to unlock the Orca and had already been able to go through the game more!
But just a problem is that I wished the other whales and dolphins can be obtained without buying with real money. I’m quite disappointed that this game can be a little greedy. Even though you may get the chorus whales, you don’t get the hero whales themselves. At least these should cost either coins or gems, but instead they cost real money. I already have the dolphin and the orca, but not the others, unless I purchase them in which I don’t like having to buy them. This game is fun and unique in many ways. But if only if the others, the Blue Whale, the Sperm Whale, the Atlantic White-Sided Dolphin, the Narwhal, and the Humpback Whale, are obtainable as well. But I would also like to see more whale heroes come to the game. I think this game deserves to include the Beluga whale, or possibly even a Bowhead whale, i don’t know, if they have good skills…. Yet you have to buy the other whales with real money. It be more fun if the other whales are also obtainable with coins and gems.

### 5/5 — I like this game! Very unique, there is just a problem…….

*2025-09-10*

I really find this game fun and interesting! As a fan of Galaga and other spaceship shooting games, this shoot ‘em up, really takes me to the waves! However I wasn’t able to continue playing as this is because a problem…. A problem when opening the app. Whenever it begins loading up, it does not open up, I waited and waited for long numerous minutes, but it won’t open up anymore. No matter whenever I try to open this app, it takes forever to open up possibly never. Like for probably 30 minutes or more, nothing happens on the loading screen. This happens all the time and yet nothing even happens and never loads up! This app really would need an update and get rid of this problem so I can be able to continue playing. But this game is fun so far, just not able to continue playing because of this problem, and this app is in need of an update so I can continue playing.

### 5/5 — Nice

### 3/5 — Good a lot of fun game🐬But..

*2023-05-31*

🐙It has a unique and different fun because it is made theme for under the sea. 
🐠There are have to buy all the other units except for the 2 basic units. 
🦀It's kind of annoying because there's an ad every time the screen changes. 
🦈The enemy's shooting speed is too fast even though it's still in the early terms. 
Above all in the boss match, it’s too much not to give a space to run away while pushing me up! 
💎Diamond rewards are too little, including daily quests. 
🩸Also, the currently health condition leads to the next stages without recover after the stage! 
and the way to recover is to turn the wheel pannel then get lucky to be pulled out 
or eat heal items while playing, 
but rarely it comes out and and it comes out at the end of the game almost!

🧭Expedition If i fail in step7 with 1d11hr left until the ends, the next challenge should be a challenge from there. But why do i go back to the first step that is already marked as finished?? 
 and, I feel bad cause some chinese&japanes marked in even though it is currently used in Korean language. Fix it !!

Your App Store title = Aqua Galaxy Attack 

Your in-game title = Sea Invaders

I found you on Twitter last year and here iz your amazing creation. I am seriously having fun with it. A very nice take on the content & Atmosphere. Your animations & action are dope to look at. I feel my dolphin getting stronger & more powerful with the upgrades. You even gave us an extra perk at different times to choose from the normal three. Your music is superb. I hope all the Bosses have different tunes. It really fits for the action at hand & W🎼W on the 1zt Boss, i wuz like where is he going?... get back here!!😂🤣 Keep up your Funtaztic heArtwork Yo!
