I only realized near the end of the scenario that I was (I assume) doing it wrong. That I was supposed to move the stack of tokens after duplicate or changing the color. I was only moving it after changing the color because it looked like it was part of the same section rather than a separate one.
In addition, it took me a good while to figure out what ‘tape’ meant. Perhaps reference something about the arrows instead or in addition. Dunno.
I did the exact same thing and only realized at the very end that you are supposed to move the stack after the duplicate and after changing color. I was like 'this cant be right, its too easy'. It makes thematic sense though on a conveyor belt. I ended up replaying the dream.
I'm glad I'm not the only one to make this mistake. Definitely the gate tile can be better laid out to be more clear on this important detail.
