Stay Alive is a free Android game developed by Sponge Mobile. It is a simulation game and an idle survival RPG set on a monster-infested island. The game is all about defending yourself against the monsters that come to destroy your house and kill you. As a player, you will have to mine, cut wood, fish for food, and gather materials from harvesting zones to become stronger.

The monsters in the game become stronger as you progress, so you will have to build your house, obtain gear, and hire guardians to face them. You can also upgrade your characters, gear, house, and guardians using Magic Stones that you gather along the way. If your house is destroyed, you cannot eat food, so defending it is crucial. The game also has a PvP mode where you can earn Rubies by defeating other players.

Stay Alive is an engaging game that will keep you hooked for hours. The graphics are impressive, and the gameplay is smooth. The upgrade system adds depth to the game and makes it more interesting. The only downside is the constant reminders to contact the developer for localization. Overall, Stay Alive is a great game that is worth checking out.
