I own a Nook Tablet and I bought Machinarium through Barnes and Noble. I have played it through and went on to write a 'Customer Review' (all good stuff about the game but with a couple of hints to help others with the constant freeze-ups [about saving their game often]) on B&N's 'View Details' - 'Customer Reviews' section.
I don't know if this is a problem with all Nooks (Color and Tablet, and maybe even the newer HD's?) or if it's something with the code in which the game was created with? My Nook Tablet doesn't have a lot in the way of options on setting screen resolutions, or whatever and I'm sure the Nook Color's are the same way. I know that Nook uses Android 2.3 OS (Operating System); Nook Tablet 4Gb with a mini-SDK 32GB (Android 2.3 OS Build MODEL (8 Gb Model): BNTV250A)). Here's a link to all the technical specs for Nook Tablet (8Gb & 16Gb):
https://nookdeveloper.barnesandnoble.com/product/nook-tablet-specs.html, just in case that helps any?
I plan on passing any info on through the 'Customer Reviews' that I get here to help other game players.
Thanks for any and all help,
