I'm developping the story and scenario of Mighty Bubbles and I'm wondering how many levels should I have considering this:

- each level will be about 1/3 the size of the current demo level
- each level is comprised in its world
- I'd like 5 levels per world
- the gameplay will be much more elaborated: I have a lot of ideas
- graphics will be by far more professional and polish
- no boss ennemy at the end of a world but the level will be much more difficult
- the public targeted is 10 to 18 years old but might be older
- I expect to sell the game 20$ US

If I look at different platform games such as Super Mario series then it seems that they have between 40 and 50 levels.

Thanks for your help.

Thanks for these very good advices! I will consider them.

agreed!

more != better

fewer quality levels would be better than many poor levels. That being said, as many good levels as you can fit couldnt hurt

The previous posts are right on target.

I cant be sure what kind of game is that exactly, but atleast in my opinion, if the player can choose which way to go increases the game value. (like that the player doesnt have to finish every level to finish the game.)

Of course it doesnt fit in every game, but in many games which have a story, it would be nice.
