Here you can see how 3D is used effectively to improve gameplay
I must admit: Major Nelson sold the game to me, otherwise it could’ve slipped past my attention.
The game is awesome. A competent Metroidvania clone that greatly improves gameplay and immersion (the dynamic camera in the 3D scenarios is astonishing) over the classic 2D formula. Chair Entertainment was really good to not go too far from a proven concept, despite the technology at disposal. Priced at 1200MSP is just a steal, it also includes 21 puzzle levels very similar in concept to MGS: VR Missions.
Technically the game is outstanding: their use of Unreal Engine 3 is top-notch. No wonder they were bought by Epic.
