Added:
- "Click-to-grab" feature: When enabled, a puzzle piece "sticks" to the cursor, so you don't need to hold the button down (thanks, TheSha).
- Option to force button icons in case automatic detection fails (thanks, r0ckarong).
- Icons (glyphs) indicating the transition to the menu and to the next level upon completion (thanks, r0ckarong).

Fixes:
- Missing lines between puzzle piece slots (thanks, maximussolini).
- Advancing to the next level now correctly proceeds to the next level listed in the level menu.
- Missing characters for Hindi.
