Linking and triggering go hand in hand, you must link two objects together to make them interact. For example portal<--->portal makes them teleport things, and button<--->gun makes the gun shoot when the button is pressed. See: Tutorial > Linking things.
The thing I don't like is that like I want to get money right? I see a pack and then a dinosaur hits me and sends me flying like ten times a game! It gets annoying like that. Another thing is that when you buy a pet you equip it and can't take it off the pterodactyl annoys me because of the dinosaurs. Like this I bought a pterodactyl I need some more speed so I cant take it off so when I hit a dinosaur I fly and waste my food. Oh and make some new upgrades like Wheels Kind of wood ( King wood best) less dinosaurs for a cost of 500(after you get all animals and food). Plus I thing this deserves an 4/5 would have been 5/5 if you made less dinosaurs.
