Ah sorry, it was more of a nitpick! Creating good experiential learning experience is certainly an art, and not something I'd expect to have nailed in a 48hr jam. My point was more that the popups detract from the cool atmosphere (although the popup ending text in my game is pretty rough haha).
And that's up to you! So fundamentally, a simple player action (jumping) is changing the player's relevant environment in a predictable manner (assuming situational awareness). Building on that with more complex environments that require the player to carefully consider when and where to jump could result in a solid puzzle game. If that's something you think you'd enjoy making, what you've built is a good foundation for it!
