The first part of The Journey Down is free on iOS today, in case you haven't checked out the PC version yet. Planned as a four-part series, this unique looking adventure game has gotten praise for its fairly interesting themes and painted backgrounds.
If you want, you can play the "retro" version of the game for free on the developer's website. If you're keen on getting it on PC eventually, stay tuned for future indie bundles, as the game was featured in the Summer Royale bundle once already.
