Idle Spire
A fantasy auto-battler built for the pocket. Field five heroes across two rows, summon a roster out of four factions, and climb floors that never stop — including while the app is closed.
Independent studio
A small independent studio making things worth keeping on your phone — deep enough to think about, patient enough to put down. Games first, starting with Idle Spire.
What we make
Idle Spire is our first release, and games are where we are starting — but we are not fencing ourselves into one genre, or into games at all. What stays constant is how we want the things we build to behave.
Nothing we make will nag you, run a countdown at you, or punish you for leaving it alone for a fortnight. If something needs your attention every single day to stay worth having, we have designed it wrong.
There is usually a real system under the surface for people who enjoy taking things apart, and a version that simply works for people who would rather not. Neither way of using it is the wrong one.
One project at a time, built end to end and shipped when it is right rather than when a calendar says so. We would rather put out one thing we are happy with than three we are not.
