Should I buy Penumbra.....?

[lukaspriest]

Here's the deal....I am currently enthralled with Amnesia...it is beyond killer, and it makes me poo my pants with delightful fear and terror. Problem is, I discovered Penumbra AFTER Amnesia.

Having only played Amnesia, would it be worth it to buy and play Penumbra? My only fear is that having played the more advanced Amnesia, Penumbra may seem old and clunky. What do you all think? I have some paypal money burning a hole in my pocket, and with the Steam sale, Penumbra sounds awfully tempting especially at only 10 bucks. What should i do? Should I buy it, or will it seem antiquated after playing Amnesia?

Thanks for your advice!
