Its not really fair to ask the C code to include OpenGL calls -- a pretty verbose API -- to compare it against the Clojure code which has default access to the Java Swing library, and GUI widgets. Looking at the game logic in both examples, I'm convinced by psykotic. Both programs are fine, but the Clojure one doesn't seem to add any extra higher level cleanliness or abstraction, over the plain old C code. Not to say that this holds in general, as code bases grow; or to take from the original tutorial in any way; just that I agree with that for a simple game like tetris, you don't see any benefit of the higher level abstractions, as implemented here. Also, you have to give psykotic some credit for putting the time into writing a quick proof of concept to back up the opinion expressed!
