ok here's what i think
1. it's a demo they'll show the damn building when the game is actually fucking finished
2. you enter the levels using his paintings like the wahoo man. i think he's important enough.
3. that's the plot of the demo, not the full game.
4. it's a demo holy shit. they replace the gates that'll be used when the full game comes out
5. you're not even RIGHT it looks FINE
