Video reference for the 20 gems of The Promise (West) in the June 2026 Next Fest demo; the full solution video is linked below.
The Promise (West): 20 gems
The West half of the demo is about colored beams rather than mirrors. Beams come from emitter blocks, and a gem placed in a socket switches on every emitter in its room. Standing in a beam gives you its power: green lets you walk through walls, cyan lets you push blocks, yellow breaks rocks. The area has a surface and darker depths. How the gems and emitters work, and how to tell if you are soft-locked, is on the Explorer guide.
The full 20-gem solution is in Joric’s West video.

Gem timeline
The Gems counter in the corner shows the gems you are carrying, so it drops whenever a gem goes into a socket. The table lists when the counter first reaches each number in the video; that is close to, but not exactly, the order in which new gems are found.
| Gems carried | Video | What happens |
|---|---|---|
| 1 | 0:10 | First gem from the starting shrine; placed nearby, the yellow beam breaks two boulders. |
| 2 | 1:23 | A gem lights the cyan beam in the lower-left room and a boulder at the end of the beam is pushed away. |
| 3 | 4:17 | Middle-right area; a green beam crosses the whole map. |
| 4 | 5:33 | Upper-right area, with an orange beam. |
| 5 | 7:11 | Lower half of the map, yellow and red beams lit together. |
| 6 | 10:08 | — |
| 7 | 10:20 | Most rooms explored by 10:40. |
| 8 | 15:37 | The map now wraps around; several cyan and yellow beams lit. |
| 9 | 15:44 | — |
| 10 | 20:05 | Gems are taken back from sockets to make 12. |
| 12 | 20:11 | Down to the depths: 12 gems fill the 4×3 socket array and light a red beam, then are taken back. |
| 13 | 23:35 | In the depths. |
| 14 | 25:07 | Back on the surface. |
| 15 | 26:26 | Depths again. |
| 16 | 26:54 | Depths. |
| 17 | 27:28 | Depths. |
| 18 | 28:08 | Surface again. |
| 19 | 30:38 | A red emitter is pushed next to a cyan one in the lower-left; its beam crosses the map edge. |
| 20 | 31:30 | All 20 gems are placed around the gold-framed room in the depths, and the area ends. |
