"I would've spent forever roaming the convention hall if I didn't think to replay the intro and scour it for them."
Yeah, I did exactly this. I didn't find any tickets in the golf game so I spent awhile scouring the convention hall looking before out of desperation redoing the intro.
The problem then is that in the Theatre you find more than enough tickets to get to the pool.
The intercom also mentions something about getting tickets via documentation in the bin(?) on the bottom floor but none of the bins seem to contain anything.
The Golf minigame felt a bit shoddy as well. I thought I had to play it up until hole 20 where I just gave up and left. With no scoring system and it not exactly feeling fun it feels a bit pointless. If the dev sees this, maybe the Golf minigame can award tickets if you get it into the hole with a low stroke?
I didn't stay up as it was an evening release in my timezone but I think for the $6 USD I spent on it, the game was a decent time killer.
