This video presents Hydra Slayer as viewed through NotEye. It presents the various graphical and geometries available through NotEye (one important thing which is not shown on the video is that you can change to a bigger resolution to see a bigger part of the map). Gameplay is not explained, if you are looking a tutorial I recommend youtube.com/watch?v=DSvJfGQXwBs .

Selected reviews:
HyperRogue, the non-Euclidean roguelike, is a mind-melting masterpiece [...] Its one of the best games Ive played in a long time, which makes it all the more annoying that I could have been playing it for a long time. (Adam Smith, Rock Paper Shotgun)
HyperRogue is a monumental example of a novel concept executed perfectly. (CtrlAltDestroy, honest gamers)
One of the most interesting roguelikes to come around lately (John Harris, @ Play)
Easy to learn, hard to master, impossible to understand. HyperRogue definitely is the one of the best puzzle games Ive ever played. (sldav on Metacritic) HyperRogue trailer](https://i.ytimg.com/vi/xAFrKKApHTY/mqdefault.jpg)

![Portals to Non-Euclidean Geometries
On this tour, portals will take us to various non-Euclidean geometries. This is not Minecraft!
A cool holonomy effect happened during this tour, but it was not explained by our guide Tehora! Have you found it? Please tell us in the comments!

An interactive version of this scene should be added to RogueViz soon. We need to make it work in VR first!
