Fun game, with interesting core mechanics. I do like that sometimes you have to hold and move on the spot to let the enemy pass. I find that the labyrinth-like level is also a good idea, except for a point I'll bring in later, but it make you try to learn the level while grabbing the gems in case you have to make a run for it.
I wasn't able to finish the game, since an enemy was camping the only entrance to part of the level where a gem was. I tried to pull it away but got caught by the others quite quickly. Even though they are ghosts, it feels a bit unfair that the enemies can go through walls once they detected you, it make it so that depending on where you are in the level, you can't escape. I'd also love to see a prompt or something that tells you once you've been detected (something my game also needs I think), because since it changes to real time, everything moves even if you are not, so it might switch when you are not expecting, and get caught pretty quickly.
