It's kinda addictive, isn't it? :) Yes, it's all procedural, albeit very simplistic at the moment:

var levelSize = 5 + currentLevel;
LevelGenerator.Instance.Initialize(levelSize, levelSize);

The rest of the code for 'Initialize' is here:

I hope to massively improve this in the future. Others mentioned that it's repetitiv and I totally agree. Wish I had more time.

Very interesting, because it doesn't feel like procedural :) Maybe because you update the seed every time? Yes, it is addictive and fun game :)
