Thank you so much for the detailed feedback, it's hugely appreciated - and is all really constructive, too!
I fully take on board all your points about the tension between the story-play, as it were ("returning bodies leads to bad things happening") and the gameplay ("return bodies to progress"), as well as the frustration of potentially losing all progress at any given moment. I actually experienced some of that myself while doing my final playtesting, and you're absolutely right that it's infuriating!
I'll consider all your excellent points in further detail, and may well rework/rebalance some of the game aspects to make it less punishing (or at least less frustrating). And yes the camera is...uh...interesting at the moment! ;) There's a lot of very clunky code going on in the background, and I think it potentially needs a full rewrite. Version 2.0, perhaps!
Huge thanks once again - I'll definitely play and review Liar's Map, it looks very interesting! :)
