Gameplay footage of the pre-alpha for The Prison at Hal Astralo. Presents opening area of the game, as well as other areas, all in various stages of development. You should watch this full-screen, or in the dark, or both. This is a stealth game with a lot of darkness in it. I tried to set the lighting levels of the video as close to what you'd want in-game. You'll notice the one spell on display in this video is "Levitate". The player holds their breath to levitate. (It's not as easy as it looks.) And of course if you hold your breath to levitate for too long, you'll get dizzy and eventually start breathing and plummet back to the ground. And although the player falls in this video, it's not from lack of oxygen, but by being shot by one of the archers.
Usually I dev alone, but some of the models and textures in this game are made by Erica Claeyssen. So lots of credit to her.
