v0.6.1

New

• Options > Extras > Add to Steam on the title screen (Windows and Linux): adds the game to your Steam library with one choice.
• A portable download for Windows and Linux keeps your saves and settings in a folder beside the game, and the normal downloads come with a make-portable script that does the same.
• Photo mode has its own Film effect filter (the d-pad Right button cycles it, and it is remembered), available without finishing the game, and the grain keeps moving.
• Options > Gameplay > Natural chains (off by default): the two chains that come down for Ico, at the Stone Pillar and in Underground 2, keep their links the right size the whole way down.

Fixed

• The main gate's glow no longer disappears with anti-aliasing on, and the Anti-aliasing row shows the setting in use.
• The Film effect now covers the whole picture on wide screens.
• The picture at 16:9 is sharp again.
• Walls, shadows and effects no longer vanish at the edges of wide screens or while the camera moves, such as the water-tower lift wall and the walls at 48:9.
• Motion is smooth with a frame-rate limit equal to your screen's refresh rate, and the 144 and 240 limits now reach their rate.
• Photo mode's right stick no longer rolls the camera when you open it from a camera looking steeply down or up.
• The boat cutscene keeps its sounds after the opening movie was skipped early.
• The touch controls show during movies on Android.
