This was really cool! The introductory text was good at setting the mood and the whole game has a really nice atmosphere
There's a lot of attention to detail, like how the interface changes if you play in landscape or portrait mode. I also realized it works on a phone, which is awesome and I think fits the game really well.
I enjoyed playing through the game, it had a nice length and challenge level. I didn't have much need to use the time travel mechanic though, which is a shame since it's such a great concept.
I liked having to figure out the meaning of the symbols and I think you had just the right number of different objects to make it fun and interesting, but not too confusing.
I didn't understand the rules behind the movement of the enemies though. At first I thought they were just stationary (but rotating every other turn). But then sometimes they move. And do they move towards me, or do they mirror my movement? I'm color blind, so maybe there was some state in the colors that I didn't pick up on?
I also had some issues with the time travel menu. The scrolling issue was not a problem when playing in fullscreen, but the menu still behaved a bit strange. When going up or down in the menu it would sometimes close and move my character instead. And sometimes all the options would show the same turn I think? It was a bit hard to figure out what was going on.
The game was pretty and fun to play, and I love the concept of the little device.
