La Cave 51: problematic of procedural generation

I tried some basic procedural generation. The main issue I found is:

• if you authorise a wide variety, then you might have some not-anticipated situations, and it is not playable,
• but if you tuned too much your generation, then it becomes repetitive and… boring!

Currently, I am going to opt for a semi-generated game: the general map is designed to have always several possible choices. For instance the keys to reach the exit door of the level will be duplicated. So I hope one key can be reached at least.

I know some people had studied the procedural generation of platformer games (they even wrote books). If I have the time I will have a look on their work. Currently I am still learning by trying.
