Cool idea, but similarly to @Haldarys, I'm really not sure what I'm doing wrong.
Spoilers!!!!!!:
The answers I put were:
Yellow:21:00, hospital, bomb
Green: 23:00, bar, hammer
Pink/Red: 00:00, beach, knife
Blue: 22:00, airport, sword
It kept saying to check my answers though, but it all seemed to line up. Am I missing something? I tried making all the ones that I did not think were correct blank and I also tried all red in addition to the ones I thought were correct as green.
