Copy Kitty is a mission-based action platformer developed by Entanma Project, which is comprised of Azure Lazuline and Raibys. Their description is as follows:
The gameplay harkens back to classics such as Gunstar Heroes, Kirby 64, various Mega Man titles, and more. The main Mission Mode pits you against single-room challenges that rack up in difficulty as you explore the different worlds. In contrast, Endless Mode has you fighting endless waves of enemies, with plenty of boss encounters and changing terrain.
The game can be both purchased and demoed here. Alternatively, you can buy the game in a cheaper bundle for a very limited time here. IMPORTANT! Copy Kitty is still in Steam Greenlight limbo, so if you like what you see/play, please support the game by giving it a vote here. Remember, if you buy the game via the site or bundle, you'll be able to get a free Steam key once the game is Greenlit!
