There's a new NES homebrew in town, one that has been in development for some time but now it's finally ready to meet the public... I present to you, INVERSION - When Darkness Cry, a game by Lucas "Dizzy9" Kur.
"Your aim in the game is to collect all keys from each map to open doors leading to next level. Use B button to change state of darkness.This will result in changing map colors and, more importantly, solidness of objects. Use springs, moving platforms, vertical conveyor belts and levers to your adventage! Satoshi is pretty weak kid- he will die if hit by anything hostile, like bullets, spikes or ghost. Also, Satoshi can't survive going off screen, so be careful."
