Not to be confused with Contract J.A.C.K.
Fix the entire plant on my first day? Well, if anyone can do it, ZACK©™ can. First, he needs his tools back.
So what kind of game is this, anyway? It's...
This room's simple enough, each button controls the set of spikes of the same colour. Pressing the same colour twice puts the spikes back. Can't tell what colour the spikes that are already down are? That's because the colour is one pixel big!
When you mess up, you don't restart the room you're in, you're put a room back. Did I mention ZACK©™ stomps as slow as hell?
Contraption Zack is a great example of why flick-screen puzzle games are almost all awful. You have no idea what the overall goal is, the things you do on one screen can have any effect on anything on any other screen, and it's possible to get trapped in an impossible room. That would all be forgiveable, but only if it were easy to move from screen to screen and easy to undo things you've done wrong. It's not.
Now we know what not do to when making a game.
