damn if it is short :|
It takes me about 50 minutes to complete it,and I've never played it.

Wow you're good! I took me an hour and a bit for completing the game (It's my first time playing this). But it was a real good experience. I'd like to play it again :)
Short but sweet and memorable

I hope to see on Gog the sequel,I watched some videos on Youtube and is very beautiful

Yeah, man. I just watched Heart of the Alien video and it's pretty awesome. But too bad in that version, Eric Chahi wasn't involved in the development. Also, the main character (Lester) died. According to wiki, Eric Chahi regretted that decision about Lester death. Still it looks pretty fun just like Another World

I've never played Heart of the Alien but the consensus seems to be that it isn't very good.

Well, I never played it too. But at least the visuals are pretty much the same and that's pretty interesting to me. Not really sure about the gameplay though. It seems slower than Another World. It has less 'survival' feel IMO.

Still, I want to play it
