Play Kyonsees 2 (japan) Online

Kyonsees 2 was a Japan only release for the Nintendo Entertainment System, and I believe it was put out by a company called Pack-In-Video. It came out during that period when the NES library was absolutely packed with action platformers, many of which never left Japan. This one fits right into that category, a side scrolling adventure that feels very much of its time.

You control a small, agile character who runs and jumps through a series of themed worlds. The main goal is simply to get to the end of each stage, navigating past enemies and environmental traps. The game's signature mechanics include a screen by screen progression where the next section doesn't scroll into view until you cross an invisible line, and a simple projectile attack, like a short range energy shot, to defeat foes. The pacing is relentless, and the difficulty is quite high, demanding precise jumps and quick reactions. Playing it feels like a constant, tense scramble from one dangerous screen to the next.
