Thank you very much for your feedback.
Well, I hope I'm right with 20 hrs -- don't blame me if I needed more.
Yes, I originally had the idea of providing at least a volume control for the music (to turn it off for example, if it's getting annoying after a while), and I'm still unhappy with the fact, that there's still the disabled "Options" menu entry. So I guess it's more a version 1.0 RC than final 1.0.
Your idea for dropping the blocks immediately by pressing a key is now on my Todo list, thanks for that. I think that'll speed up the gameplay a lot.
What do you mean by a tutorial? Describing how to write a Tetris-like game with SFML? I kinda thought about this some days before by myself, since I'm so thankful that Laurent wrote such a great library, that I want to give something back to him and of course to the community in general.
But I got a better idea.
I have started to develop a library called "SFMLGame", which will provide useful mechanisms for programming games, like I used them in my Tetris game. This library will be built on top of SFML. When getting to a usable state of development, I hope to make Tanktris available as some kind of tutorial project for SFMLGame. My primary plans for SFMLGame are to provide the developer with common classes like menus, automated animations, config/savegame loaders and writers etc. But this is still heavily in the pipeline and needs a lot of time and work to accomplish.
Oops, a lot of "Blah blah" in my posting not really thread-related.
Again, thanks for your motivating and constructive feedback. I thing I'll implement both of your ideas.
