From what I could see, you've got a good setup for a "collect the falling items" game. The biggest problem by far is the size of the screen - I zoomed in my browser as far as I could and I still could see very very little. I see that you submitted this game to the LowRezJam as well. Did you accidentally mess up the display somehow? You can have a low resolution game and still have a larger window.
I did play until the bar was filled up, but there wasn't a win screen or anything (that I could see). I think that if you just fixed the window size, you'd have a decent little game here. 🙂
(Also: when I finished the game, it tried to open up a URL somewhere? I don't know if that's a GDevelop ad or something you put in, but it was weird. It feels a little like something a virus would do. I have no doubts that your game is clean, but you might want to see if there's something you can do to prevent that. It felt a little off-putting and might keep people from trying your game.)
