Down Deep

A one-tap mining game for iPhone.

Stand on a rickety lift and break the column of earth beneath you, one tap at a time, before the cave-in above catches up.

How we work

Few things. Finished properly.

  • Small on purpose

    One clear idea per game or app, built carefully and finished. We would rather ship one polished thing than three half-baked ones.

  • Data kept light

    We collect what an app needs to work and nothing more. Shift Vault has no account and no servers at all: your data stays on your phone.

  • Fair to play

    Every Down Deep run that counts towards the leaderboards is checked on our server, so the top of the table belongs to real players.
