I'm still so amazed that this game suddenly blew up recently, after years. It feels really cool for all my friends to now also know about this gem, and I'm really glad that you're future proofing the game with a sequel built from the ground up to work with that fame :) I'm also extremely happy that there's gonna be a mobile version in the sequel, being able to play the game anywhere is a great feature I'm glad we're keeping. And, last but not least, your commitment to keeping v1 up as long as possible, then swapping to open source, is exactly what every game should do and I couldn't be happier.
One question, unrelated - are you ever going to add Chromebook support, or at least WASD movement support, to the Android version? I play on my Chromebook a lot, and it's hard to use the Android controls with a mouse. Possible, of course, but it's lacking in finesse.
