- Release Version: 1.013 - 26 October 2023
The last few weeks added a lot of fixes - every day updating Happy Lab. Today is a Scream Steam Event - and we are ready to release the game. "1.013" is kinda of a symbolic number for a release on Halloween too. I tried to keep the Demo version up to date - but at some point, there was no time for it. At this point - the full version is our priority.
- 1.000 Update: Release Date! - 11 October 2023
Hello everyone, I'm excited to share an update for the Demo version with you. This update comes packed with fresh visuals and revamped level designs. We've also introduced more challenging puzzles and added some emotionally expressive bots to enhance your gaming experience. The game now boasts a whopping 5,000 words, and we've included full voice-over support throughout. Additionally, we've implemented comprehensive controller support and key remapping features. Without further ado, here's a sneak peek of the updated Room layout and some of the captivating Bot emotions: We can't wait for you to experience these exciting improvements in the game. Stay tuned for more updates and enjoy the enhanced gameplay!
- 0.973 Update - 30 July 2023
The most major change - is a new Input system from Unreal 5.1 Remapping keys is now possible. Besides that - not many changes to the sandbox, as we are currently working on Story Mode. We have probably added more bugs to the sandbox - but that is a topic for the next update. PS If you already played the Demo and have a save - your gun will jam at the begging of the game. Just change it via mouse wheel to another gun to unjam. I will fix it in the next update =) Changelog: Input System Keys Localization Input System Dupes Cheat Added: Teleport after Win Cheat Added: Ghost Mode Updated Creepers Added: Hero Health Comp Added New Creeper Logic - Attack Hero New Step: Max Work Time New Daily Step: Working Time Added New Glitch Level 11 Added 14 Level Updated End Demo Updated Level 9 Added FX Ice and Logic Firedown Levels Updated: Block Cube Added Fixed Stairway Updated Stairs and Added New C…
- 0.970 Update - 6 July 2023
Hello, this is the first update after the Demo release on Steam. Many things were reworked and updated. Most critical - Trap Building. It was totally reworked - now it is smoother and offers some 'hacks' like building Cube on another Cube without the player moving to higher ground. Most critical bug - traps double trigger on the first trigger after being built. (Thx Sever for founding it). This bug was nasty - fixing it changes damage values - so we have to adjust some Story goals. full changelog: First Double Trap Trigger fix Replacing Turrets Demo End wnd update Demo Lootbox GUI for Demo End Traps Claws Added German language support Added French, Vietnamese, and Japanese languages with universal font Added Chinese language support Updated new languages Updated localization Physics Lootboxes Added Radio Music VSync enforced by default, added as an option Added collectables Building Upd…
