The game format: if I want to understand that Scratch does not allow you to export a game as a standalone exe file, I am surprised that we can offer a proprietary file, which is without specifying the software to play it . So I had to do a search to find that I needed Scratch, install it to finally find out how to launch the game to test this game (since I'm not familiar with Scratch). I don't doubt the effort put into making this game, but don't forget that a player shouldn't go through such IRL steps, at least if they aren't meant to be part of the game itself.
The game itself: this game is quite basic. A few fairly standard levels, but where the character has far too nervous reactivity. It would be good to revise the speed of the movements downwards. For the rest, the game offers a beginning, an end, sound elements, personal graphics, ... it's not so bad.
