For level 1, do you mean that gap right before the section featured in the screenshot? Cause if so, that's intentional: You can cross it with enough speed, but it's meant to be something that players will likely fail the first time around before they learn about Maya's momentum. And that's okay, because failing the gap jump just gives you the opportunity to learn to wall jump instead of punishing the player. I thought that part was actually some of my best level design, cause it's a split route whether you make the jump or not, and either way it can teach something new about how Maya controls.
The main focus of the game as it is right now is to serve as the foundation for everything that follows. The current levels are meant to be somewhat challenging (partially to push the limits of Maya's controls and better improve them, partially just cause I'm personally more fond of challenging games). But I'll be the first to admit, level design is an area where I'm not nearly as competent. That's why I put a lot more focus into the level editor, to give people the opportunity to make levels better than I can. I have a somewhat decent idea of what kind of game I want it to be, but I know I can't explore it's full potential on my own.
