Designing a Shooter Around the Mouse, Not the Gamepad
Most space shooters are designed for a gamepad and then adapted to a mouse. We did it the other way round, and the game came out different.
A thumbstick and a cursor are not two ways of doing the same thing. A stick gives you a direction and a rate. A mouse gives you a position, instantly, anywhere on screen.
Almost every design decision downstream of that changes.
Aiming is not the challenge any more
On a gamepad, pointing at the thing you want to hit is a meaningful part of the difficulty. With a mouse it is nearly free — a competent player puts the cursor exactly where they want it, immediately, every time.
If you leave the rest of the design untouched, the game becomes trivial. So the challenge has to move somewhere the mouse does not help: how much is happening at once, how quickly the screen state changes, and how often you are forced to choose between two things you cannot both reach.
Which changes what enemies are for
With aim solved, enemies that simply need to be hit stop being interesting. What works instead is enemies that make you decide.
Something that is about to leave the screen with points on it, while something else is about to reach you. Both are trivially aimable. You cannot do both. That is the actual game, and it only exists because aiming got cheap.
The collection loop
The stars started as a scoring flourish and ended up as the spine of the design. They pull the cursor away from where safety is, which is the cleanest tension a mouse game can have — the input that makes you powerful is the same one that makes you vulnerable, because it can only be in one place.
Two platforms, one input
The game runs on Mac and on Windows through Steam. Keeping a single input model across both was worth more than adding a second one for either.
Gamepad support keeps coming up, and it would not be hard to add. The reason we have not is that the difficulty curve is tuned around aiming being effortless. Handing a player a stick would not give them a different control scheme — it would give them a harder game, tuned for someone else.
Where it fits
Short runs, no progression, everything decided by what you do in the current thirty seconds. If that sounds thin, it is meant to — the whole design assumes you have five minutes, not an evening.
