So, so cute! And some really, really fun game design. There's a lot of moments where the game choreographs its mechanics in a very natural way. Learning to really take advantage of saving the jump until the middle of a fall felt like a gamechanger, especially once I realized how many of the levels reward taking that movement. The combination of that + control over the light source + fall damage + the energy both being time and dependent on how much you extend the light source really just made the whole thing blend together so well. I also liked how it felt like I was able to information-gather a lot from failed runs. And the art is super cute---loved making the little guy shuffle back and forth, haha!
Slightly decreasing the time that the platforms stay still would definitely help keep things moving/make repeated runs feel a little smoother. I definitely get the tension of wanting to increase some tension from having to wait as the energy ticks down, but it definitely got tough at some points because of that (especially because, from the nature of the game, you can't see much in the meantime!) For QoL, I'd also remap the continue button to be the interact button on the level clear, rather than the restart button. These levels definitely do feel speedrunnable (and I'm tempted to do so haha), so maybe the restart button can be the default when replaying a level, but I did definitely restart a few levels on accident because of hitting the interact button a few too many times when finishing.
So much charm and life in the game---loved all of the death flavor texts. Great work, and thank you so much for sharing!
