Never actually played this specific tomb raider part, but i can tell you that you nailed the original tomb raider feel and play style. The timed puzzles are awesome and gave me some serious nostalgia.(favorite being the rolling cube with the fizzle field) Felt like I was playing a great Tomb raider level, except I had a portal gun. Two thumbs way up!

Very beautiful. Great adaptation of the Tomb Raider games.
