Update 4, Steam next fest participation and the future for updates
Thank you! This will (probably) be the last update I will upload for the prologue. Thank you all for all the feedback, nice comments, sharing highlights and the ideas! These allowed me to make the necessary QoL improvements and bug fixes before releasing the game in ~3 weeks. Next Fest On the 5th of February, Steam next fest starts and I will be participating. Playing the demo and sharing it would really help me out a great deal!! As for updates, I will probably only update the demo, but the updates will only contain QoL improvements and bug fixes. So no extra content updates! Future updates As mentioned, I will only be updating the demo from now on. These updates will mostly consist of some balancing, QoL updates and bugs. I still look at all the feedback and ideas given in the discord and the discussion pages! Update 4 Here are the changes I made for this update, maybe I forgot to list some. - Added a recipe book - Added more visibility when building a new tower, can also be turned off in the Game Options - When zooming out, it the type of tower and crystal to give you a better overview - Updated the look of the voxels a bit, added a bit of color variation - You can now swap crystals from one tower to another - Increased the difficulty of hardmode a tad - Added a section to the handbook about status effects like DOT, bleeding, slow etc. - Added Windowed mode option! Fixed various bugs/inconsistencies - Fixed issue with leaderboard not loading when fast pressing buttons - Fixed issue with game over damage not being accurate - Fixed issue with boxing glove - Fixed issue where the continue button would still show up after winning/losing - Fixed the issue with not unlocking the big burger when receiving 3 sandwiches - Fixed a bug when re-rolling and sorting that would result in different outcomes - Fixed the bug where when loading into a game, the screen would go from windowed to full screen. - Fixed more bugs that I forgot to write down... The new look! https://i.img...Read full article on Community Announcements (timgamedeveloper)Patch NotesOfficial
