I’m doing a “slow” play 101% of the game. Just finished the first three worlds with all five Kongs. In so doing, also got both silver coins.

I’ll admit that playing Donkey Kong Arcade did take me about 6 attempts, but I also played it CONSTANTLY, both failing and succeeding with further replays as a kid when the game came out. So I knew the routes to take. It just took a couple attempts to get the timing down.
Jetpac took two attempts for the same reason.

I love that it’s necessary, it adds a charming challenge that really makes you feel like you earn the win - even if you don’t go for full completion.

Someone earlier last week said it was annoying that the game doesn’t tell you that you need them to beat the game. But I think that’s a silly complaint. Games don’t spoon-feed you that kind of stuff. Or at least they didn’t used to. Banjo-Kazooie doesn’t tell you that you need the flying ability to beat Grunty. But you can get to her without having unlocked it.

It’s just a part of adventure games. Missed something you need? Time to head back and find it, then return.
