that little movement of the background corresponds to the player's (player moves left -> playfield moves right and vice versa). and it is obviously intended by the author. It gives an illusion of a wider space, or of a certain depth of the games' world. at least that's what it does make me feel and i'm sure that's what the author wanted to achieve. so IMHO it's a good thing and a feature that should stay in the game.
Sorry, but i don't understand the sense here. Maybe better, when the programmer itself answers here, cause the question was addressed to her. No attack on you TYREX, but how should a left/right jerking of the background-graphics give the player an illusion of a wider space or more depth in the game? Then i could also argue, that a non-smooth scrolling in a horizontal "jump and run", brings a wider depth into this game. But how should that be the case? Normally totally smooth scrolling is the goal that programmers want to reach for their games, never heard anything else.
All my retro-gaming-friends and i, perceive this small jerking in "Neutron" as a little bit disturbing. The eyes then goes automatically to the strange jerking objekt and not to the enemies where they normally should be. A totally smooth scrolling gives a better and more realistic feeling, while flying over a landscape or over big enemy spaceships. And this jerking here can also not be designated as something like an earthquake that is happening right now on the ground, because when this would be the case, then the earthquake/jerking would also come, when the player don't move his ship. But it comes only when the player does, so it has something to do with the player and this is the strange and unrealistic thing here. I think, this is not only the meaning of my friends and me.
And furthermore, a version WITH this small jerking already exist now and people who like this, can use this version then. So it would be a good idea, to bring a version now, without the jerking. Then everybody can be satisfied. Don't understand me wrong, i know that the game already is very good and that this maybe is 'complaining' on high comfort level. But especially because i think, that the game is really good, i ask here for further improving it by wiping out that disturbing little jerky left/right background-movement.
