Hi I was wanted to know how can you design a level for side-scrolling shooter that doesn't become difficult or to boring? For example how does the placement of enemies or powerups affect the gameplay?
Is there a way to make it balanced or does it not matter for this type of game?
The reason I'm asking this is that when playing these types of games they usually have certain areas where you're safe from enemy fire which are basically gaps in which the bullets don't land. Is this purely based on luck that this happens or is there a way to prevent it based on how the enemies are placed?
Any ideas? Thanks!
