Basically a full, free, DLC for portal2 with as much high quality content as the actual game. Unbelievably good, and I feel guilty not having paid for it. Seems to only way to support Portanis (the author) is to buy the soundtrack on bandcamp: https://portanis.bandcamp.com/

Few things for new players:
1. There's an occasional bug where the block doesn't appear in the future. If this happens just reload the level. It's not an extra challenge, just a bug.
2. If you find yourself wondering why you can't place any time portals (after you're given the ability to), it's probably because you've gone through one of those brown/orange meshes that look like a forcefield, or you need to find one to go through. They sometimes enable/disable time portal placement sometimes and it's not well explained.
3. There are no puzzles requiring any mechanical FPS skill. If you find yourself trying to get some finnicky split second timing or perfect aim, your solution is not the intended one.

the custom maps make this the best puzzle game in the world
