I've checked the PS Vita version and the iPad one and I can't find the option to see what items these people have used. I'll check the Android one later, though. I've just seen that there are consumable items like a Super Head Start that automatically play the first part of the run for you. It's an advantage that can be bought.You have Jetpack Joyride totally wrong. It isn't pay to win at all, in fact, the highest scores I've seen are by people who don't even use any IAP (consumable items).
I'm not saying it should be something different. I gave an example of why I don't like certain practices. You can get everything in Jurassic Park Builder without ever spending any money at all (aside from timed items you might not have the money for when they're on sale) as well.Jurassic Park Builder is a freemium game through and through, that's like complaining an RPG has RPG elements in it. There's a million games like Jurassic Park Builder, and it's just what they do. You're free to not like them, but it's not setting out to be what you want it to be, it is what it is.
If you want to have things now then you'll have to spend money just like in Jetpack Joyride. If you don't have enough coins then you can buy them in the store. You can unlock everything if you're willing to spend money and then there are limited use items that will just be gone.
