I noticed that when using the mouse, the ghost doesn't jump until I release the button, that makes the mouse controls less responsive and in turn harder to play, so I stuck with the space bar. Sorry, I didn't test it on my phone, but this is what happens when I went full-screen on my computer: 
and it stayed that way even after I exit full screen. I'm using Chrome.
The game is too simple and repetitive, most likely you already know that. I think any new mechanic would make it better.
Thanks. I had recently noticed the mouse needing to be held down to trigger the jump. I was going to look into making it more responsive, especially since mouse/tapping is the only jump control in the mobile version.
I also was informed about the full screen issue by someone using Firefox on a desktop PC with a large screen, though it worked fine on my 15'' laptop. What kind of device are you using? Setting full screen to work properly seems to still be in progress with GDevelop and I am hoping to work some more of the bugs out.
