I'm going to have to vote for a different game each day...

If there's a continuation would it be of the best ending or could there be alternate following episodes, each from a separate ending?

The ones where Saira manages to use the teleporter could be really cool.

Yeah, that seemed to be the gist of it.

The only thing that I didn't like about it was that the graphics on the main part (don't know the proper name..) was boring half the time, but the back and foregrounds were cool enough to make up for it.

The problem wasn't that it was being slow, it kept changing speed which can be annoying if you're trying to avoid bullets, sometimes it seemed to be going too fast. It's not so bad now though.
On the plus side slow speed helped with the challenge planet.

And I did try the demo first, I'm not that stupid   

umm... I pronounced knytt right...

Can you buy serial codes after buying the game or do you have to buy them all at once?

All the reasons that
have been said, mainly because
it's made by Nifflas

And it might be a
good game too ...uhh... nanana
