[Bug] Cannot get collectables

[Stevoisiak]

I was playing Toki Tori 2, when I moved one of the larger creatures into the suction tube. Now, any time I try to walk past, the suction tune transports me. I think I lost my chance to get 3 collectibles.

I don't remember anymore if you can reach it from the other side. Probably not. But I think to remember that the suction tubes will stop after you have completed the storyline. So just get back there after that.

That kind of stinks. The OCD in me will be bothered for the rest of the game.

The door should close after you go through it, or at least that's how I remember it, and it should definitely be closed after you finish the game.
If it's still open after that, then I would be very curious where it would lead, but saying that might be a bit spoilerific, which is why I used spoiler tags.

Yeah, seems I have to wait until I beat the game for it to be closed. Which kinda sucks.
