Hey, thank you for the feedback! It really means a lot to us to know how to improve. On our game page, we linked this guide to hopefully help players better understand the controls and it would be great if you had a look and could tell us if it's helpful.
About luck vs skill, jvthewanderer started playing our game on hard mode, essentially, to only use the yo-yo and jumping. While it took him 4 HOURS to finish the game on hard mode, half-way through the stream, he got pretty good at it, and there were A LOT of close calls, you can watch these for yourself here. Knowing this, I'm not sure there's more luck than skill, and you can also slow down to bring the difficulty lower, and he definitely demonstrates that. Nevertheless, in some situations I do agree that it may be more luck than skill. Thank you again for taking the time to comment!
