Achievement browser and selectable skins! They'll have to be unlocked by reaching certain milestones, such as: total number of items collected, total number of levels played, high scores, and placing on the leaderboards!
I have also started working on SFX - I'm thinking of having two selectable sound schemes for folks to choose from: beeps and clicks. I know some folks with hearing sensitivities (I have some myself) and so its important to me to accommodate all types of sensory needs with the game!
Finally, I added some light visual animations to @jordancarroll 's AMAZING VO work - every 40 points, he will pop in to encourage you to keep going!
Every day brings us closer to a finished product! Based on rumblings I've heard in the Playdate community regarding Catalog Drop dates, it is looking like, if accepted, XTRIS would come to catalog late January or early February.
