Most puzzles were simple, a lot of mechanics are introduced
but without much building on them.

Soundtrack is not bad on its own, but started to annoy me by
the end. Too repetitive.

Developers did a great job at world building, various email logs and
personal diaries in areas between puzzles tell a lot of backstory, dialogs
with T.O.M. create a solid build-up to _something_ but... It is not
happening. Ending is completely anti-climatic, you just shot
these sluts while playing as T.O.M. and then there are credits.

Game visibly borrows a lot from famous Portal series but fails to
match its quality.

Try The Talos Principle instead.
