Let's trade feedback! I submitted a project too.
Gameplay & Reccs: The double-jump is super tricky. It may help more to add a trajectory arrow or a radius bubble to the character. So while I have the mouse pressed down, that type of visual helper would appear so I know where I'll likely end up based on where my mouse is and the angle. Some jumps were oddly unpredictable. I'd also recommend the software or height of by jump be connected to the length of my mouse press. Pressing down for a long time charges the jump to a greater height. Where a quick press of the mouse results in a smaller jump.
Art Style: This works well. Your level designer did their job. I feel brought into the world well with the way the first part of the level starts, waking up from an accident of some kind and trying to get back to my sons. Simple story that works here.
