I don't seem to find the solution to unlock this one scene. 
Can I get another hint?

Hi !
On the first floor, the alien hacker gives you a pink remote in exchange for the green crystal.
Use this pink remote on the cyborg on the second floor.
Alose, you can find a blue remote (a bit hidden in the right side) on the first floor.
Use this blue remote on the cyborg on the second floor to get the “alternative” version 🍆.
(and it’s also possible to use the magic wand on the alternative version of the cyborg).
I'd also suggest widening the screen or moving several objects as some of them are on the edge and frustratingly missable. At least three items I didn't even see because they are half cut-off or more by the screen's edge. But, I mean, those are very small complaints. So, all things considered, great game. Would like to see a lot more floors in the sequel, if you make one. The elevator concept is a unique spin on the point n click genre. Kudos for originality! It made me feel like I was playing something unique and new!
