Not bad for a first level - quite easy to figure out, and the design isn't bad. You can autopilot right from the start, but it isn't necessary.
Hi and welcome to the party. We have a pretty big bag of tricks that we use around here, most of which are based on B's autopilot motion feature. Which makes reaching the water possible from most of the elevators in your level and ends things pretty quickly. But the look is very well balanced, with a nice twist to the path. So nicely done for your first level. I'll look forward to seeing more. Spoiler: Autopilot trick
I did it as intended and got wet but you left two areas where you can tap on a slider, B starts to run but if you move the slider, B will fall into the water.
