Development update: 2nd Free DLC delayed
Hello,The 2nd Free DLC isn't coming out on the 3rd of September. I'm sorry. Here's what happened. The new stuff looks the way I wanted it to look. That was the whole point, modern graphics because of the time travel, and I got there. What I didn't expect was that with the new content in the build, the base game and the 1st free DLC started running worse. Areas that were fine six months ago are chugging now. It's not the new levels being heavy, which I planned for. It's the old ones getting dragged down with them, which I didn't.I'm not going to ship you an update that makes the game you already own run worse. So it's delayed until I fix it. I'm not going to throw out a date to make this post land softer, because then I'd be back here in a few days or a couple of weeks writing this again. I'll release the date as soon as this gets fixed. Thank you for your patience!Read full article on Community Announcements (Ashnell Games)AnnouncementsOfficial

Patch Delayed One Week – Voice Acting Preview Video
Hey everyone,Quick update about the patch that was supposed to launch tomorrow March 6.After some last minute testing, the team and I decided it’s better to delay the patch by about two weeks. There’s a new gameplay feature that still needs fixing, and we don’t want to push the update out until it’s working the way it should.When this project first started, it was just me working on the game solo. Thanks to all the support the game has gotten, I’ve now been able to bring on four additional developers and 7 voice actors for the main game / 1st free dlc, and 16 on the 2nd free dlc, and we’re all working together to make the game bigger and better than it was originally planned and release.My goal for this game is simple, create the most epic version of Grandpa possible at not extra cost to you guys that have supported the game. Please trust me that this update will feel and will play like a new game because all the old code was remove and we created a new one.I’ve also attached a preview video showing one of the big changes in the update. All of the AI voices have been removed and replaced with real voice acting except for Grandpa. I’m still searching for the perfect voice for him, and trust me… he deserves the right one.Thank you all again for the support and patience. It really means a lot, and the dev team, Voive actors and I are excited to show you the update very soon.Read full article on Community Announcements (Ashnell Games)AnnouncementsOfficial
