NovaBirch Interactivea games label of Taymount Diving Ltd · Aberdeen

Games that give your hands something to do, slowly.

NovaBirch builds small Android games with no accounts, no connection and nothing to buy once the download is finished. The first is Cogtender, an assembly game about tools, parts and taking your time.

bench notes

A calm game should not be in a hurry to be finished with you

Most tactile mobile games treat the gesture as a formality: swipe, the animation plays, the reward lands, the next thing is already asking for attention. The satisfaction is borrowed from the animation rather than earned by the action, which is why it evaporates after a week.

Cogtender goes the other way. A step completes when you actually perform it — hold steady until the part seats, keep turning until the thread bites — and nothing on screen is racing you to the end. There is no timer, no score multiplier and no advert waiting for you to finish, because there is nothing in the app to sell. What is left is the quiet part: a bare shell, a set of tools, and enough time to do it properly.

No timer

Nothing on the bench moves until your hand does. A build takes as long as it takes.

No interruptions

No advert between builds, no reward video, no prompt to buy a shortcut past the fiddly bit.

No connection

Every build ships inside the download, so the app works the same offshore, underground or on a plane.

COGTENDER

a quiet bench for careful hands · blueprints · tools · assemble

A slow, satisfying assembly game about building intricate devices one precise step at a time. A piece sits in front of you — a different shape and layout every build — with the tools laid out beside it, and the job is simply to put it together properly.

Each build breaks into small tactile actions that use the whole touchscreen: bring the right tool to the right spot, press and hold to seat a component, tap rapidly to drive a fastener, drag in a circle to turn a screw, swipe to wipe and polish, trace a path to route a wire. Tools snap into place when they belong there, and a step only completes when the action is done correctly — so it has the rhythm of actually assembling something rather than watching it assemble itself.

Three actions, nothing attached to them

The gestures the game is built on, taken off the bench and laid out on their own. There is no device here, no sequence and no build to finish — each one just does what it does, then resets.

Seat the bushing

Press and hold until it sits flush.

Drive the rivet

Tap quickly — it settles back if you slow down.

Turn the screw

Drag round and round, clockwise.

waiting

Three isolated actions with nothing behind them — no blueprint, no order of operations, nothing that becomes a finished object. Cogtender is exactly that missing part: a shell in front of you, tools beside it, and a sequence that turns the two into something built.
