I think you need to give clearer instructions. I believe I found the exit, 3 blocks stacked to look like a gate, but moving through it did nothing.

After teleporting around a bunch of times I decided to try and find the Minotaur which was a lot harder than it seemed. The Minotaur moves way too fast and in seemingly random directions so the chance of it running into the player is very low. I managed to catch up to it after teleporting and I heard the weird sound effect but then it immediately ran away.

some suggestions:

• Make the environment an actual labyrinth and not a massive open space. In a labyrinth you always feel like your making some progress by deciding whether to go left or right. In this massive open space it just felt like I was holding W and waiting for something to happen
• Make all the portals the same model. I kept finding blocks of different shapes that I thought were unique objects, but they all just teleported me to a random spot which was very confusing.
• Give the Minotaur the players position and have it track the player down. This game could get very exciting if the Minotaur actually did its job. Imagine hearing that terrifying sound and then frantically trying to run to the nearest portal to avoid getting caught

You’ve got a good foundation for a game here, but it needs some work
