When you play a scrolling shooter what features tend to make you enjoy it or want to play it more?
By scrolling shooter I mean the games like the classic Aero fighters series or Raiden.
List any number of features you like that draw you to that kind of game.
The reason for my asking is that I am going to make one and would like to please as many people as possible, If I made it solely on my prefrences I feel it may not please others.
So please if you have any prefrences list them for me.
Please don't say graphics... I can only do so much...
Also the poll above is to ask what levels and kinds of difficulties people prefer. Basicly as example [Easy, Swarms of enemies] means that there would be enemies that move in groups in patterns and [Average, Swarms of enemies] would mean that there would be a lot of enemy swarms moving in patterns kind of thing. I'll basically balance out the replies I get when designing the levels.
