The first GDevelop game I saw this jam.
Firefox was completely bugged and unplayable for me, Safari was better but might have been clipped a bit.
I got the game but could not figure out the movement at all even after reading the description, so how I played was basically somehow letting the auto movement get me into the position.
I cant always tell whether my attack landed unless I look at the score, so improving that feedback would be the first suggestion.
The second would be an interactive tutorial, that would convey the movement mechanics maybe, because that I could not get at all.
But the reverse fisheye effect and the game in general is pretty cool and innovative.
Congrats on releasing a cool game!
