The Speed Demo linked here pretty much proves that, since he does in effect cover over 90% of the game without using any hacks or exploits. Ä7 = 17 minutes of game = 40 cents a minute.
It's a puzzle game!!! That's like reading a walkthrough to The Secret of Monkey Island, and then complaining that you could complete the game too quickly/easily.
Your first time through Another World should take you a good few hours.
Don't watch a speed-run for this game, people. You'll just spoil it.
That depends on your definition of joy. If getting kicked in the nuts over and over and over and over while being subjected to a ridiculous plot is your definition of joy, then HoD is an absolute joy to play.
Another World is tolerable, because it's old - but let's leave HoD in the crapper where it belongs.
Oh my god. I feel deep deep pity for your inability to appreciate such a wonderful game as Heart of Darkness. That's absolutely tragic.
