All my progress got deleted and when I try to play the game again, clicking the new game button doesn't do anything. Clicking continue brings me to level select but nothing works there. I'm not quite sure, but I feel like that wasn't intended.

It might be that your save file somehow got corrupted. Go into your Appdata\Local\AtC_BB\Saved\SaveGames folder and delete the .sav file. After relaunching the game, it should create a fresh save file and hopefully fix the issue. You will unfortunately lose your progress, but the game should function properly now.
