This is an old mappack a friend of mine and I made during what was left in our last year of high school. It was done mostly in an attempt to make our own portal maps and to be creative during our free periods and during our lunchtime.
Please be aware that this map is unfinished and wasn't really intended to be released in the first place and was only meant for us to play, so it includes some cheap and difficult puzzles and platforming in it. Also, checkpoints are an issue, so I'm very sorry about that.

Have some screenshots or something:

Credits to Desktop Ponies for the RD sprite which ended up not being used at all.
