Developer Description

Manage a fish tank of guppies and other aquarium creatures

In the game, the player must manage a tank of guppies and other aquatic creatures, and each stage begins with two guppies in the aquarium tank. Guppies and other fish drop coins, which can be collected by the player and used to purchase fish food and upgrades, such as more aquatic creatures, food that can keep the fish full for a longer period of time, and laser upgrades to repel attackers.
This is a virtual pets simulator with a blend of elements from action, strategy, and puzzle video games. The game can be played in five modes: Adventure, Time Trial, Challenge, or Virtual Tank. In Adventure mode, a player advances through four tanks, each with five levels. In each level the player must earn enough money to buy three egg pieces to advance to the next level. During an initial playthrough of feeding fish and fight against aliens, at the end of each level of a tank, the player receives a new pet from the egg. While 28 pets can be earned throughout Adventure mode, each level requires the player to pick three pets. Each pet can aid the player during gameplay. There are bonus rounds where the player can collect shells, which can be spent to place fish in the Virtual Tank.

This is a perfect port or remake of the original, except that it is missing the screensaver function at this moment. Maybe it doesn't work that well on a phone, though, so if that's the case, then this is still the 5 stars I am giving it!

The game is so nostalgic and great! I'm loving it!!! However, a few things I've noticed that's a bit different from the original; 1, the upgraded food pellets do not satisfy the guppies' hunger for longer periods like they're supposed to, and they don't increase the coin drop rate. 2, the aliens do not invade the tank past the third appearance. 3, the guppies should not be transforming into blue kings as quickly as they are. I love this game so much, but I wish it were a bit more challenging! 💜

Fun game just some of the helpers don't work as intended on the mobile and the alien cyclops you can't hit it's attack back at it. like in the computer version.

★★

Good substitute but doesn't work 100%. the main thing is the aliens can not kill the fish. There's a couple bugs with sound. It does look like they made be updating it as time goes. So may get to a point where is more like the original game. But not worth the price

1. The HP for the blue alien and tiger alien are too big, it doesn't make sense for early level. Dev should be rebalance it. 2. Nimbus the manta ray, does not rush toward food instead just swim normally. In original version, Nimbus will move asap toward the position where both food or coins drop just like Rhubard the hermit crab rush toward fishes to snap em from the bottom of the tank. 3. Gumbo the angler fish, does not attract all fishes just like in the game. Maybe bug.
