Game Boy Classic - Tail Gator

Developed and published by Natsume, Tail 'Gator is a likeable sidescrolling action-platformer for the Game Boy. As the story goes, a dragon warlord known as Basso Gila teleported his castle and armies to the peaceful kingdom of Moberry, which is populated by anthropomorphic beings. Basso Gila intends to destroy Moberry and extend his power, but the council of elders of Moberry send a highland alligator named Charly in order to stop Gila and his forces.

Charly's main method of attack is his tail. He also has an HP meter consisting of up to seven hearts (with five at the start of the game and after every continue used), as well as a power meter. When the power meter is filled up to seven P's, Charly's tail whip gets a projectile shockwave for a limited amount of time. The game is composed of five "areas", the first three of which contain four levels within. The player is free to choose which of the four levels in each area they want to finish first. These four levels are arranged based on environment, having Air (sky/clouds) on the top, and Land (hills) below that, Cave below Land, and Underwater below the Caves. One of these levels will have a boss. The first area has the boss in the caverns, the second area has the boss in the underwater section, and the third area has the boss in the mountains section - these take on the forms of a frog, fish, and otter.
