Update v1.3.3 — HexLemma Steam update #1581333

v1.3.3 Bug fix: Daily challenges now always play in normal mode. With Hardcore on, a daily was starting in hardcore — hiding the mistake count and letting wrong moves stick, which skewed the leaderboard. Bug fix: Earned achievements now survive Purge Save Data. Purge still wipes puzzles, history, daily progress, and campaign progress, but no longer clears achievements you've already unlocked. Bug fix: Settings checkboxes are now visible in the Dark theme. The Skip-intro / Distraction-free / Swap-mouse / Hardcore boxes were drawing an un-themed glyph that vanished against the dark card.
