You can't shoot as far as I can tell. I just run into things. This game is currently under review to see if it should be removed as it technically is possible to play it right. I currently have submitted the top score possible as far as running into things goes.
Temp files are in one of two locations.
Press the Windows Key + R. Windows key is to the left of the sapce bar and has a flag on it.
That opens up a run prompt.
Type %temp%\low\arcadeox
Press enter.
If it does not find a folder then change it to
%temp%\arcadeox
That is the folder that contains your temp files.
The games are in the storage folder.
The save states are in the other folders.
