Annwn is now on to V1.2 - this is a minor version update focused on gameplay/quality of life improvements and bug fixes.  This build is significantly more polished!
Change log:

• Added tile magnetisation to help lock cursor to the correct tile (can be adjusted in Options)
• Moved energy bar to the bottom where it's easier to see (can be reversed in Options)
• Fixed 1-frame cursor lag, cursor is now rock solid
• Fixed game over happening while mid-leap to escape
• Disabled submerged totems so you can't leap to instant death
• Fixed bug where particles would flow to/from the wrong target
• Fixed incorrect timestep causing jaggy particle movement
• Fine-tuned particle settings so they flow better
• Minor polish on menu transitions
• Optimised island generation to reduce CPU spikes
• Lot of invisible groundwork for forthcoming features

I'm aware these fixes have been a long time coming and aim to update more frequently going forward.
Roadmap:

• Time trial and challenge calendar
• Tutorial rewrite
• Controller support
• Localisation
• Known bug: trees floating in air (something to do with tiles the Watcher has interacted with in the past)
• New gameplay features (save games now store version number so I can maintain backwards compatibility)

At Insomnia I received a lot of great suggestions from players which are significant blocks of work; time trial ghosts, multiplayer race mode, level editor... leave comments if you'd like to see any of those or something else!
