Controller support added — Shoot 'm Up Steam update #81999

As requested I've quickly implemented a basic gamepad / controller input layer. The entire game should be navigateable from A to Z and completely playable, albeit there are some caveats; - Hints and tips will still display keyboard / mouse names - I will have to refactor this so I can show actual buttons.. But for this I need more controllers as well. - Car controls are a bit funky, you'll have to use the joystick instead of trigger buttons to step on the gas. - The game is much harder with a controller, as there is no aim-assist. - You can't re-map controls yet (only configure the movement / aim speed) in-game. If you want to edit those, you will have to fiddle with the button numbers in the "settings" file located here: %LOCALAPPDATA%\\ShootMUp\\settings This file is an INI file that will contain a section of "GP_CONTROLS". The numbers there relate to the numbers you see in the Windows...
