the break out achievement can be unlocked after getting all stars in rusty lake hotel game.

Considering these games it might mean something but at least with a quick search I can't see it being talked about. Did find a handy timeline on reddit though, that must've taken a long time with these games going back and forth

[raineyday]

Oh for sure. I was just calling attention to the years these particular ones take place and wondering if that little detail is meant to be meaningful.

[Cece09]

Yeah the devs even mentioned the whole order, its not just hey play cube escape then rusty lake. its a hey play 3 games of cube then rusty, some more cube and rusty then you can finish up

[raineyday]

"It is suggested you play through Rusty Lake Hotel before attempting this one. This game resumes after hotel and even includes a secret code from it"

An observation I've made: "Hotel" takes place in 18 93 and "Birthday" takes place in 19 39 . I wonder if that's not a coincidence. This whole series is extremely well crafted.

[Cece09]

Glad you managed to get it. Thanks for pointing out the mistake, changed it to the cat as there's no mouse in site just a fish

[螺吸混]

Thank you. I found that achievement.

In Grandpa's pocket.

Do give the fish to the cat

[Cece09]

Oh whoops. I was thinking about the mouse trap. Its suppose to be the cat I believe. I went through each game 3 times should've picked up on that. The achievement you mentioned is for finding the note on grandpas person. The most trouble is getting it to actually open to read the clue but its simple to see

[螺吸混]
