pixelBOT EXTREME is an arcade side-scrolling shooter that looks like it was born in the 16-bit era of Super Nintendo and Mega Drive.
The game consists of pixel artwork, a retro soundtrack, and a really high difficulty level. It's even that hard, that dying and respawning is a core mechanic of the game. The biggest twist of the game is the color-based shooting mechanic. The player can shoot rockets in 4 different colors by pressing the respective colored button on the controller. Each enemy is colored in one of the 4 colors as well. They can only be destroyed by shooting them with the correct color.
When playing in couch co-op mode, two players play as a team and split up the colors. Only when working together, they can survive to reach the next checkpoint.
