In my video game (in the making), Joe Text Adventure, here are the static sprites for the first batch of enemies. The first level in the game features the first two, and each level after that presents one new enemy. The game is 32-bit and a 2D platformer. The names of the main character is "Joe Text" and he wields a flamethrower. The names of the enemies appear under them. Keep in mind that the game is unfinished. Here are some descriptions of the enemies and what they do, in case you're still reading this :p
James Hammer: The main villain's (John "Flathead" Bowler) first ever robotic creation. He moves back and forth and isn't much of a threat.
Shellbert: His movement is similar to J. Hammer, but he goes much faster
Rocco: A living rock. If you notice, his entire face appears to be spray-painted on. His health is abnormally high for an enemy.
Rozaro: Chases the main character and can phase through walls. Attacks with a swipe as he nears you.
Woody: Inspired by the Deku from zelda, this guy stands still and spits out nuts. Time your moves correctly to rush under his fire and kill him quickly.
Slurpent: My personal favorite. Slurpent hides underground, and springs up to surprise you.
Spida: Hangs on the ceiling until you are near, than leaps down and gives chase.
B-Bear: This creeper likes to chase you like some of the other enemies, but this baddie can leap onto platforms to follow you . He is the smartest, AI wise.
Puffinstine: He flies slowly above shooting electric bolts of lightning. Leap into the air to kill him.
Stan Hammer: The more lethal cousin of James Hammer. He gives off an electric charge.
Smitty 2.0: A reinvented version of the villain's failed project. He is like a standard enemy, but is invisible until you near him.
Icera: Blows cold air at you to freeze you, than tramples you.
Ogrecon: A hideous Ogre-Robot hybrid. He can't see you until you come close, but then charges with deadly speed and accuracy.
Wow, thanks for bearing with me here. If anybody cares, I can post more characters/enemies/enviro nments from the game later.
