Hey there! Thanks for checking out Aquamarine. We took down the files for the original Kickstarter demo because we are giving the game a major overhaul for our next crowdfunding campaign. When that launches in the next couple of months, we’ll have a new free demo available for download. :)
Thanks for being patient with us in the meantime! If you want to stay updated and receive early builds of the demo, we have a mailing list and a Patreon you can join.
