Gem Miner TD changes
Massive demo update is here! But first, an important announcement.
The original release date was December 12, 2025.
After a lot of thought (and reading tons of your amazing feedback), I’ve decided to postpone the release to January 20, 2026.
🗓️ New Release Date: January 20, 2026 (Mark your calendars, or just hit that Wishlist button and let Steam do the work!)
I’ll be honest, with all the recent coverage, excitement, and feedback, things have gotten a little overwhelming… in the best possible way. Reading, analyzing, and replying to all your feedback takes a lot of time (who would have known, right?).
I might be a perfectionist, but this isn't just me tweaking pixels for another month. I want to make sure I'm actually listening to all of you and that the game you've been waiting for is worth the wait.
So please, let me cook just a bit longer! 🍳
And come throw your ingredients to the Discord channel! (or email, post to Steam discussion channel or comment here! I want to hear it!)
Rest assured, there’ll be a big launch discount! And btw, this absolutely does NOT mean that there will be no free content updates after release!
Thank you all for your patience, feedback, and incredible support.
Now, on to those patch notes… 👇
