How to Play Reactor
Quick start
- Move with the trackball and approach a particle.
- Use Energy during contact to push it harder.
- Knock particles into a full set of control rods to shrink the core.
- Place a decoy to redirect a dangerous swarm.
Controls
Trackball: move. Energy: strengthen collisions with particles. Decoy: place a limited lure at your position. Avoid the outer kill wall and the later vortex.
Reactor — About this game
Reactor makes contact a weapon instead of treating every collision as a failure. Move the player device into particles and push them toward the outer kill wall, taking care not to be knocked into it yourself. The growing core steadily reduces the room available, but sending particles into a complete set of control rods shrinks it again. Energy strengthens collisions, while limited decoys redirect the pursuing particles. Destroying both sets of rods also restores a decoy for later pressure.
