I have been repeatedly having failed attempts at projects that were too large in scope for me, so today I decided to narrow my scope. I wrote up a small game similar to Fruit Ninja, but with Pi symbols for the upcoming Pi Day!
Engine: I used pure LWJGL with a neat wrapper I wrote that allows me to encapsulate 99% of the OpenGL commands 
I know the game isn’t much, but I was happy to actually see a small project get completed

I will happily post Linux and Mac builds if there is interest (I just need to change one line in the build.xml file)
