Excerpt: Quantum Conundrum has a very weird and public creation story. During 2009 one of Portal’s 1 and 2’s main designers, Kim Swift, quit Valve in order to work for Airtight Games. The explanation was that her ideas weren’t being used in Portal 2; she thought they were good ideas, and they parted ways.
Conclusion: It's not that Quantum Conundrum is bad, but more that it's not as good as what it's trying to outdo - regardless of how many people say 'But it's not Portal!' in the well-meaning, not-copying sense, the truth is that it's not Portal in the charm/humour/fun stakes instead.
Summary: Quantum Conundrum – это отличная идея Ким, загубленная посредственным исполнением Airtight Games . Несмотря на симпатичную графику и увлекательность на начальных стадиях, проект быстро скатывается до однообразия и откровенной скуки.
