Now in my opinion it's best to upgrade the rocket first. Parachute is slightly useless, radar level 1 is just fine, stamina isn't as important, so rocket, launcher, patagium, parachute, stamina, radar in that order to fully upgraded. I didn't get all the achieves so please message me to fill in the 4 blanks
