Can I convert my android app to a .exe format? I have to design a game and I thought Android Game!!! Well... Close read over the rules I need to have it in a .exe format with a working keyboard and mouse input. So am I screwed or am I going to be lucky tonight?

.exe is a windows executable. It is only executable on a windows machine. android is based on a linux kernel, so, natively, it would have to run .bin files, though native files are not executable directly. you need to go through the dalvik VM and exeute the bytecode via a .apk file.
