Well made and cleanly executed! Good job! I got around 28(?) crystals before I got lost and couldn't find anymore. I'm not sure if there's an actual ending or not. The controls felt good (when not under the slow effect), but my mouse kept going off game and click stuff on my other screen. The full screen export shouldn't be borderless window (I think that's the setting name?). The atmosphere was really nice here with a good use of dark darks and light lights, creating great contrast and mood. Well done :)
