An el-cheapo Foddy clone, which provided its challenge to a competent level...

Given the dev has another game 'Just Ski' which has similar mechanics but provides procedural generation as well, I would say there was an opportunity to add more to this game, if not procedural generation, at least maybe more than one mouintain, meticulously designed to provide the specific challenge in its intention, but also means some sections are purposefully obtuse to deliver on that vision.

Take note the achievements are insanely difficult... My 1st finish had like 2400 successful jumps and over 1000 failed ones, which included jumps where you don't care how you land as you're just making distance.... But there are achievements that demand 100% perfection with no failed jumps.

So this might not be one for achievement hunters unless you specialize in rare achievements. Most might just frown at its obtuse implementation. Like you wanna tell a dev yknow what... you should first finish your own achievements before you're allowed to dictate them to others.

But whatever... It's like a Flash Foddy game and did just that for the 7 hours I played and didn't expect more than that... If that's your expectation then that is what you will get.
