Upflux

Upflux is a neon arcade challenge about timing, focus, and clean routing. The full conveyor stack stays on one screen. Tap an orb, tap above the conveyor one level higher to drop it there, and repeat until the orb reaches the reactor portal.

What starts simple turns into a high-pressure flow state quickly. More orbs appear, belts get faster, falling deliveries need saving, and reactor surges push the pace harder still. Power-ups briefly change the flow by slowing time, freezing or reversing belts, restoring energy, clearing the board, or pausing new spawns. The timing of each use matters as pressure rises.

It is the hardest of the three games on this site, and the one that punishes panic most.

Where to play

In your browser, Upflux is free to play with no download or account. You pick up and place orbs between belts, use six power-ups to control a surge, and keep a local high score on the device you are playing on. There is no global web leaderboard or cloud save.

On Android, Upflux is available from Funlit Games on Google Play. Tap an orb to lift it one level at a time, rescue it before it falls from the edge, and push it upward into the reactor portal. Different conveyor layouts change the available reaction space, while Slow Motion, Freeze, Reversal, Auto Lift, Energy Surge, Safety Net, Reactor Pulse, and other power-ups change the flow of a run. You earn credits as you play and spend them on those power-ups when the conveyor stack gets out of control.

The Android release also supports Google Play leaderboards. That service belongs to the native app; browser scores remain local and do not sync between devices or platforms.

Design notes

Upflux keeps every conveyor level visible on one portrait screen. An orb can be lifted one level at a time: select it, choose a landing point above the next belt, and read that belt’s direction before committing. The simple input keeps attention on timing, spacing, and the flow of the whole stack.

Each conveyor layout changes the available reaction space. Wide belts provide room to recover, while tighter arrangements demand earlier decisions. Faster belts, falling orbs, and reactor surges increase the pressure without changing the basic interaction.

Streaks reward quick, clean deliveries. A missed orb also removes a large chunk of reactor energy, so each rescue is a real tradeoff: save the orb when the route is clear, or accept one loss when chasing it would endanger several deliveries already lined up.

Strategy

Read the direction and speed of the next conveyor before lifting an orb. Drop it with enough room to travel safely, then prepare the next lift before it reaches the edge.

Build streaks from orbs that are already lined up for clean deliveries. Losing one orb is costly because it removes a large chunk of energy, but a desperate rescue can cost even more if several other orbs fall while your attention is elsewhere.

Save power-ups for crowded moments. The Android release includes Slow Motion, Freeze, Reversal, Auto Lift, Energy Surge, Safety Net, Reactor Pulse, and other effects that change the flow of a difficult sequence.

How the scoring actually works

Deliveries recharge the reactor and add to the score. Quick consecutive deliveries build a streak, making a prepared line of orbs especially valuable. Reactor energy also drains throughout the run, and a missed orb takes away a large additional amount.

Those systems create a situational choice. Saving a falling orb protects its energy and may preserve a streak. Letting it go can be the stronger play when a rescue would pull attention from several orbs that are already positioned for consecutive deliveries. Judge the whole screen before committing.

There is a full breakdown in the scoring guide, and a gentler on-ramp in the beginner’s guide.

Common mistakes

• Watching one orb for too long. Check the rest of the stack before making a rescue.
• Dropping too close to an edge. Leave enough belt for the next lift.
• Ignoring a missed orb. Each loss removes a large chunk of reactor energy.
• Breaking a prepared streak for one rescue. Sometimes accepting one loss protects several lined-up deliveries.
• Spending power-ups during calm sequences. Their value rises when the conveyor stack becomes crowded.

Will it run on my device?

Upflux is a 2D browser build designed for portrait play on phones and desktop browsers.

It is built in portrait so the complete conveyor stack and reactor portal remain visible. On desktop, the play area appears as a portrait column in the middle of the window.

Touch and mouse use the same two-step interaction: select an orb, then choose its landing point above the next conveyor.
