I am using free version of lite-C and as far as I know the one I downloaded from this site originally is still only free version available. It is February release still if I am not mistaken.

As for commercial versions, I would rather see first whether I can make at least 80% of the game I am working on currently, before I buy it. Things are looking promising and I am really looking forward to finish this game. But I am still not too optimistic, considering that I am dealing here with POINTER based language which means... a lot of possible unsolvable trouble. Memory leaks, uncatchable phantom bugs due to some nonsense in the memory, etc...
