I added a substantial new built-in level to the game. Now when you go to 'custom maps' from a fresh install, you will see this at the top:
This is a pretty big new level - a Roblox-inspired Obby (short for 'obstacle course'). This is a long series of 99 mini platforming challenges, with checkpoints after each one - it looks like this (you zig-zag up and down from v. easy on the right to to somewhat challenging on the left):
It took me over an hour to beat it on my first try, and was pretty fun. On my second attempt, with friends, it took ~ 90 minutes (and was even more fun!).
So, as of the latest test builds today, table_obby is now included in Oeuf by default!
