Rubinite Controls Guide

Movement and Basic Combat

Rubinite is a top-down 2D dark fantasy boss rush from Cup Dog Games where you control Princess Ruby through tight arena fights against Blood Recipients. Movement uses WASD on keyboard or the left analog stick on a controller, and Ruby can attack with quick slashes that chip away at minor enemies but deal negligible damage to bosses. The real combat loop lives in Focus — hold the Focus input to mark Pure Blood Crystal weak points, stack up to three marks, and release Critical Thrust for meaningful damage. Every boss fight in the demo and full game assumes you understand this rhythm before you ever worry about advanced Talisman builds.

Steam lists full controller support alongside keyboard and mouse, which matters because Focus timing is frame-sensitive. Whether you play on Windows or macOS, take a few minutes in the hub or tutorial to confirm your bindings before challenging The Beast. Rebinding is available in the settings menu for most combat actions, and Steam Input can remap Xbox, PlayStation, and generic pads if the defaults feel awkward on your hardware.

Focus and Critical Thrust Inputs

Focus is mapped to a shoulder trigger on gamepad — typically R2 on PlayStation-style layouts or the right trigger on Xbox controllers — and to a dedicated keyboard key in the PC layout. While Focus is held, Ruby enters an aiming stance: she cannot freely reposition except through dodge rolls, but she accumulates Pure Blood Crystal marks on the Blood Recipient you are facing. Marks cap at three, and each mark can be spent on a Critical Thrust that lunges toward the marked weak point for heavy damage. This is not an optional advanced technique; regular attacks alone will not clear demo bosses in reasonable time.

Critical Thrust fires on its own input once at least one mark is active. One-mark thrusts are fast and safe for learning patterns; two- and three-mark thrusts hit harder but require longer Focus windows where a single hit resets your progress. Many players alternate between aggressive perfect-dodge Focus chains and conservative one-mark pokes depending on the boss phase. Talismans from Wichiwi can modify charge speed and thrust damage, but they never replace the need to press Focus at the right moment.

Dodge, Healing, and Hub Recovery

Dodge grants brief invincibility frames and is your primary defensive tool while Focus is active or when reading telegraphed boss attacks. A perfectly timed dodge — rolling just before impact — can grant instant Focus stack progress, rewarding players who stay close and read animations instead of panic rolling away. Spamming dodge without following up on Focus leaves you with low damage output, so the skill ceiling is learning when to dodge for survival versus when to dodge for offense.

Ruby carries a limited healing flask into each boss attempt. Use it during predictable downtime rather than mid-combo panic heals, because Blood Recipients punish greedy recovery. When you die, you return to the castle hideout hub where Roy handles training and story beats and Wichiwi spends Blood Dust on Talisman research. Blood Dust earned during a failed run is kept on death in the demo, which encourages repeated attempts without total progress loss.

Platforms and System Requirements

Rubinite targets Steam on Windows and macOS with a July 22, 2026 release date. Minimum specifications call for 8 GB RAM; the pixel art presentation is lightweight, but dense boss VFX and particle layers can still stress older integrated GPUs during Guardian Faye's second phase. Check the official Steam store page before launch for any last-minute spec updates, Steam Deck verification, and language support lists.

The free Rubinite Demo is the best way to test input latency and frame stability on your machine before buying. Focus charge speed and perfect-dodge windows feel noticeably worse below a stable 60 FPS, so cap background apps and verify vsync or frame limit settings if charge timing feels inconsistent. Controller players should confirm Focus sits on a comfortable trigger; keyboard players often bind Focus to an easily reachable key near movement.
