SiNKR 3 is the culmination of the SiNKR minimalist puzzler series. It offers a new slant on the familiar contraptions with new diagonal layouts, billiards-style physics and BY PLAYER DEMAND: multi-step undo. The new undo functionality will even let you undo accidental level resets and allows for banking your progress on the toughest puzzles. https://store.steampowered.com/app/1705580/SiNKR_3 The game will have a short demo available during the October 2021 Steam Next Fest with a full release shortly after that. The original SiNKR and SiNKR 2 will be receiving backports of the new multi-step undo and other quality of life improvements sometime this year. If you have any questions or comments, feel free to post them in the brand new SiNKR 3 Steam forums. Thanks!
