Hey thanks for checking it out! This is due to a last minute fix - I disabled the new game button in the web version because it crashed the game. After the rating when uploads are possible again I'll fix that.
You can reach the first person view though via the editor by following these steps:
1. Open Editor (Top Left Button in menu)
2. Via the file Menu, open "test.level" file
3. Press tab key to toggle between editor and first person view
