I'm not working on ANY free software at the moment (this game was created in about four hours over a couple of days, specially for Halloween) - not because I don't want to, but because I have to work on something, for iOS and Android, that might bring in some money. The future of my job is not secure (I was told that it might not exist from September, but it's still holding on in there, but i don't know for how much longer).
I love DinoDefense - it's probably one of the best games I've ever done, but I don't have the luxury of working on it at the moment.
