• Progression fix: a wave could get stuck when an enemy was trapped inside a triangle obstacle. Resolved.
• Steam leaderboards: no more duplicate entries for the same player across sessions. Your best scores always rise to the top.
• Fullscreen: the on/off toggle finally works properly on the Steam build.
• Top 10 submission: on Steam, your Steam username is pre-filled — one click to confirm.
• Options: "Change name" removed on Steam (tied to your Steam account).

Thanks for the feedback that made this patch possible!
