A 3D puzzle-platformer with a time-shifting mechanic and minimalistic storytelling is a pretty good idea, but unfortunately, I think the devs bit off more than they could chew here (their previous game was a free first-person puzzler called Frame of Mind, which seems to have gotten a generally warmer reception). Platformer basics like the feeling of general movement, camera, and pushing blocks around are just horribly janky here, on top of a lack of feedback for puzzle-solving elements (you'll frequently flip a switch and have no idea what exactly it did); it all just feels more like a free student-made game made in a few months than a commercially released product, even one that's currently $5 at full price, and which I think I bought on sale for less than a buck. Enjoyed some of the platforming and puzzle-solving for a bit, but ultimately it's just too unpolished on a basic mechanical level for me to recommend.
