good game but the ending can be better though

It's a nice project you have here. It's really refreshing to see a Scratch game with proper sprite animations. You can probably use the code you have to make something bigger in the future.

One critique I have to give is the pushable block. Having it the same color as the floor and walls really makes it blend in. I'd recommend making interactable objects like that stand out more.

now make a longer game that makes real use of the mechanic you made
