I know a lot of people didn't like the bats (I liked that they were difficult to be honest), but I always found the tricks to catch the player out absolutely hilarious!
Like the part where you chant and the fireflies spell 'watch out for that bat'- but the bat gets closer and closer so if you see the full message it gets you!
And the one in Exoddus too, with the 'pull lever for assistance', that crushes you with a boulder in Fee Co.
Reason I say is that I always felt this added to the tension, in that I couldn't trust the game! something so routine as chanting becomes threatening, and this was for me a key part of AO/AE- feeling vulnerable constantly. Games in general have gotten a LOT easier in the last few years, I really hope Abe HD remains frustratingly difficult!
Oh also, anyone fancy a trophy for completing the game without dying? (Not even a single time?
)
