One of the few places you can't enter right after you get the map in Hyperbolica is the NEMO art gallery. You have to find the ticket first and it is quite far from the museum entrance…
My brain wasn't ready for non-Euclidean gaming…
Most of Hyperbolica's world can be explored at your own pace, without any major roadblocks. But the NEMO gallery is an anticipation, requiring a ticket to enter. But the game doesn't give you a single clue that would reveal where to find it. So how do you get the ticket to the gallery?
The trick is that you're not the one to find the ticket to the Gallery – instead, it's the role of your trusty sidekick, Cornelius. He gets you the ticket after you collect two platonic crystals, which are in one of the other stages. When you leave the scene where you got the last crystal, Cornelius will congratulate you and give you the ticket.
If you really want to get into NEMO quickly, you'll probably want to get through the easiest steps first. Infinite Café mode, for example, is pretty easy to finish. The same can be said about the Maze of Apoiregon, as it can be easily navigated using a map. It doesn't matter which crystals you get. And even though Cornelius mentions that he'll wait for you in the gallery if you decide to do other stages first, he'll still come with you, so don't feel pressured to go there immediately.
