Some great news were posted on the NESWORLD Forum a few days ago. User Shiru announced that a new NES homebrew was ready to be played by the public, and it looks quite playable.
Here's what Shiru wrote...
The game is a logic platformer. You control a hero and his alter ego. You have to switch between them to clear a level. It is a bit similar to Binary Land.
This game is a port, or maybe a remake, of recent ZX Spectrum game of the same name. The original version created by Denis Grachev from RetroSouls, you can see video of it here and get it here. NES version got new graphics, original music by Kulor (composed for the game), and some other changes.
