I appreciate that you made your core mechanic not super hard to handle.
As someone who isn't that good at platformers I was able to complete it without problems and enjoy it start to finish while comfortably interacting with the many required uses of your main mechanic.
When I encountered similar mechanics in jam games they are often quite janky but you managed to make it actually pleasant to use the drawn lines and their springboard effect.
I would have loved to see the asylum aspect being more present.
Some phrases written on the walls or so would have made the story way more clear. Right now it's only really portrayed via the description of your project / submission page. Also it would have given the world I traverse as a player more meaning.
