Well, the map was fun for 5 seconds before I realized all of the problems it has. Please excuse the textwall, but I have to rant a little. It's a great concept, but it's just not executed well.
As interesting as it looks, I'm afraid I have to say that this map could never work outside of 1v1s. For starters, everywhere I went it was cramped. I understand that it's supposed to be a playground, but if it's going to work in TF2, there needs to be space. Right now it's claustrophobic. Also, the playground is designed like a maze, and that's never fun. I took the intel and got lost fairly often. Speaking of which, the intel is in a very bad spot. It would be virtually impossible to take the intel even if there is just one player guarding it. There is only ONE pathway to the intel, and it's a cramped, steep, and very uncomfortable stairway. Then you have to pass the enemy team's spawnroom, and then finally get to the intel. Not to mention that you are vulnerable at every part of that journey, and it really is a journey because once you finally get the intel and take the alternate exit (because you aren't allowed to go back), you will be trapped in a confined space where someone is definitely going to be waiting to kill you whilst you try to figure out where the exit is.
Furthermore, there are a couple of gaps in the ceiling/floor that someone can drop down from or where a soldier or demo is supposed to jump up through. However, the gap is so small, that it's virtually impossible to line yourself up perfectly to slip through. Therefore, it creates various dead ends that every class other than soldier and demo can go through, and even then, going through the gap offers no real advantage over going the other especially when it takes more than 5 tries to get through.
Also, there is random death pith behind the slides that is pretty useless. In fact it's almost as useless as the stairway that is behind the slides that leads to nowhere. However, that route is still better than going through the "underground" section as seen in the first picture because unlike that route, going across the deathpit is not entirely a death sentence.
I would also complain about how strange it is having "ball pits" that are actually reskinned water pools if it weren't for the fact that using trigger_push would mean only being able to use strafing to move through the ball pits.
Overall, it's a neat concept, and would probably only work in idle servers. Except, the map has far too many issues that stop it from working well at all. The map is far too cramped and is just frustrating to play in.
