About Radium

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.

Features:



• 130 levels of increasing difficulty
• Unique physics-based game controls
• Automatic zoom and scroll function
• Polarization change
• Pure minimalism

Головоломка интересная, пазлы и разнообразие прикольное, есть элементы спидрана некоторые. Прошел все на отлично, пришлось немного попотеть. Единственный минус этой игры - сохранение. При сносе вашей операционной системы весь ваш прогресс теряется. Имейте это в виду!

*Radium*, developed by Lukas Jaeckel and published by Develobster, is a tightly focused physics-based challenge that builds its entire experience around precision and control. It does not rely on narrative, spectacle, or layered systems to hold attention; instead, it leans into a stripped-down design where every moment is about mastering a single, unusual way of moving through space. This minimalist approach gives the game a clear identity, one that feels both refreshing and demanding depending on the player’s expectations. The defining feature is its control system, which replaces direct movement with force-based interaction. Players guide a small sphere using two beams that push and pull it across each level, creating motion indirectly rather than through traditional inputs. This immediately sets the game apart, as movement feels less like steering and more like manipulating momentum. Early on, this can feel awkward or unintuitive, but as players begin to understand how the forces interact, the system reveals a surprising level of depth. Learning to control speed, direction, and positioning becomes the central challenge, and even small improvements in technique can make a notice…

Get ready to be highly annoyed by this little tractor beam platformer.

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.
