Hello! Yes the devs have said it will be able to be played on mobile, but the graphics will be worse than a desktop.
In order to play the game you will need at least one crew member, each wallet can have up to 5 active crew members at a time. Generic Adalians with no bonuses will be able to be minted for $10, so a complete crew of 5 for $50. Generic Adalian minting will be enabled once StarkNet is ready. Currently there are only the Arvad Crew Members on OpenSea, they are limited and have bonuses
