I love and enjoyed the risk/reward factor of staying out and building the bridge but risking losing progress when you're attacked suddenly. It's a unique concept for a game that I didn't see anywhere else in the submissions that I played and I didn't find any bugs. Although I'd make it so the explanation/speech at the start of the game is in a static box at the bottom of the screen with a picture of the player character to the side of it sorta like in RPG's so it's static and easier to read.
