[Spoiler] Thoughts, questions, and sequal idea

[Romulator]

2. I'm still not sure what the deal was with those tentacle things you could poke that eventually start sucking more of your hand was, game-mechanics wise. After finding out what what WAU was, I stopped poking them, but I was never sure what they were doing in the first place. I also felt that if they were helping, perhaps there was going to be some later drawback caused by having used them or even an trophy that would be dependent on either not using any or using them all. I'm just confused about this.

After using the first one and it heals you, Simon comments "It doesn't hurt anymore". Furthermore, when Simon uses one while Catherine is around, he remarks how it helps take pain away, despite the consequences of hooking up to the WAU. Hence, it hints that it heals you without displaying a hint (since Frictional Games comments on stuff about having all hints at the start of the game and are not too intrusive).

If you were to use only one WAU flower (the first one which you must use) throughout the whole game, you get a code in the ARK's survey terminal which combined with 5 others were used to open the supersecret.rar.

Also, adding a spoiler tag to your title, since it is likely to promote such discussion
