Hi, I've removed my entry because I have misread the rules and didn't really qualify for the jam. You are still invited to have a look at my game, if you like :-)
Click: A on Steroids
I quite liked the game. I was curious as to how it worked. I assumed you used XNA but didn't pick through the DLLs much. Also, you have a Linux version which to my knowledge, puts XNA out.
It's a custom C++ engine. Uses OpenGL for rendering, SDL for input, audio and fonts and that's basically it :)
Bonus points in my eyes. Most aren't willing to brave a new engine.
Still a great game! Good job on creating it!
