Polished production. The use of a timeline works very well here and the meeting yourself traveling back in time is a great concept, if a bit unpredictable. Hope to see a sequel or at least some more levels. A level editor could produce a huge amount of new content. Setting puzzles might be almost as much fun as solving them.

Difficult to overstate how BEAUTIFUL this game is and how much care the dev clearly put into the design and the puzzles. The puzzles are all challenging and feature innovative ideas (time travelling teleporters!). Unfortunately however, the controls are a bit clunky / unintuitive (on-screen indicators for up/down would help). Additionally, the game drains too much battery to repeatedly use as an on-the-go puzzle game. Will definitely keep an eye on the developer's other efforts though.

This is a really solid puzzler. It has plenty of content and quickly gets rather challenging. To me, it lacks that extra something that would make me give it 5 stars, there could've been a little more polish here and there, the game could've had a little more personality but overall it is still a very good game well worth your time.

Game is not giving achievements. Specifically, Level 104 (this is the only one I have gone tried since noticing I have zero achievements in this game) 🌟🌟REVIEW🌟🌟 This game is a terrific logic game, I would say it is easy, but things that are easy for me logically, generally aren't easy for others. But, this IS a 5-star game through and through! Why my low score? Because it isn't giving me my achievements. When this is fixed, my score will be adjusted for accuracy.

Boring and has nonsensical controls. Why would swiping up and down go backward and forward in time when the timeline indicator uses left and right, rewind and fast-forward icons indicate left and right, and every video player on the planet also uses left and right? Update: Comfortable motion is not a good reason to make it like that. Swiping forward to go backward in time and swiping back to go forward in time is still a terrible idea. The timeline at the bottom is not an equivalent alternative.
