echo-commentary, cyberpunk platformer. really good, even if odd designed - very labyrinthine levels that may seem strange if you play this after 2 and "worse" when thinking about it on 3. turns out, though, that it is way better replaying it than playing for the first time - some levels that may seem gigantic, after recognition, you can finish them pretty quickly. the future/past mechanics are very well implemented, because it not only sustains the environmentalist message but also the levels has big linear spaces and loops for you to use or creates challenge where losing your momentum is losing the time-travel. love the bosses!! they are fast and smartly designed. the music rocks too!! really a sonic masterpiece and after replaying, thinking if it could be my new favorite . . .
