Really cool game! It felt like the hitboxes we're a bit too big at some parts though, and sometimes the 'z' button didn't work to restart a level.
I know, the "z" button problem is an engine problem, for some reason it stops working if you use it too much. Thanks for the comment! (And yes, hitboxes are a bit big, I did what I could with the 72 hours, it was my first time using GDevelop 5)
