Update notes 21/12/2025 - achievements and (initial) level editor — Spell Slide Steam update #32553

Achievements added. Level editor added (currently only for 'Spell Slide' world levels - more functionality to be added in future updates). Thank you Sergiu: compressed images == smaller size. Thank you Dohi: adjusted escape behaviour on options menu accessed from a level - now it returns to the level rather # than level select; updated word definitions, allowed words and hints; fixed typos and tidied hints; fixed fullscreen mode so screenshots can be taken. Maybe steam overlay works now?
