First off, apologies for the time in between updates, I'm genuinely just terrible at predicting how long things might take, and have prioritised straight up coding and bug fixing over pretty much anything else in my life right now.
It's almost ready. The last few bugs are being ironed out and the finishing touches added to the new (and greatly improved) soundtrack. All the store assets are ready now, so the new version will be launching with trading cards and 21 new achievements.
When will it be out though? As soon as it's ready really. As long as the bugs continue to be squashed and we get the soundtrack ready, hopefully in a couple of weeks.
Here's a short video I mashed together in the mean time:
