Evaluation
Radium launched on March 13, 2015 as a self-contained minimalist physics game with 130 levels. The store description presents a fixed feature set with no mention of additional content, DLC, updates, or expansions — the game was designed as a complete, finished product from day one. There are no DLC listings and no developer communications announcing planned additions to the game. The developer's attention has since moved on to a sequel (Ra², later released as Radium Lux on February 24, 2025), which is a separate product on Steam. The original Radium has received no post-launch content updates and was never positioned as anything other than a complete package.

Radium Lux (the sequel) launched on Steam as a standalone product — the developer's work on the franchise continued in a new title, not through updates to the original Radium

About this game
Radium is a physics-based skill game, featuring unique game controls. A game which avoids any non-essential elements and focuses on the elementary minimum.
Navigate the ball through the levels, by controlling with two tractor beams that exert force on the ball. In some levels you need to collect tokens to activate the exit.
The polarisation change is simple but challenging. By collecting an item the interface changes to yellow, the ball falls upwards and the tractor beams pushes the ball away.
• 130 levels of increasing difficulty
• Unique physics-based game controls
• Automatic zoom and scroll function
• Polarization change
• Pure minimalism
