According to my dictionary (Collins):
'shortcoming' - a failing , defect or deficiency.
'shortfall' - 1. a failure to meet a goal or a requirement. (It doesn't matter about 2!)
Well both words fit!
I've just finished Part 1 of the game & just loved it! - it was everything I hoped the game would be... so far!
I thought the 'shortcomings' were pretty minor like 'drags' in dialogue & after clicking on 'actions' before anything happened, also I agree that there were a couple of voice actors whose accents weren't perfect e.g. Nico's but they're just nit-picks which really didn't spoil my enjoyment of the game. N.B. I'm no expert but I think Hobbs' accent is UK Yorkshire?
I liked the pacing of the story also the humour although possibly some of it is essentially English which doesn't translate too well & not appreciated by all English people either!
I liked the character of Navet with aspects of Inspector Clousseau but without the charisma & less funny but he still made me laugh!
I really liked the puzzles ranging between easy to a little more challenging & thought the make-up one, silly or not, was a lot of fun!
I'm now about to start Part 2
