Con un guión bien cuidado y unos puzzles muy entretenidos, nos da una experiencia de juego genial aun no siendo muy bueno resolviendo problemas como en mi caso. Lo recomiendo!
Me ha sorprendido Sphenoid gratamente . Un buen juego en primera persona que crea una atmosfera de terror psicologico, con muy buenos puzles y un gran argumento por un precio mas que justo, y mas teniendo en cuenta que es un juego Indie. Enhorabuena!
It’s a pretty rare treat to find a pure escape room style puzzle game in a legitimate horror setting, and Sphenoid nails it. It’s got really great puzzle design, slow-burn horror atmosphere (with occasional intense scares), and a solid prison/hospital setting. It’s not the most polished game, there’s definitely a pretty low-budget look to some of the animations and characters. But it still manages to satisfy that dark blood-soaked asylum feel. Pretty much every puzzle is well-made, zero moon logic. The only thing that got me stuck was some hard to see hot points. But otherwise it was a very smooth and engaging escape room puzzle game in my favorite kind of setting! Wish there were way more games like this.
