I am really impressed that you managed to make a very nice looking game on Scratch. I just love the art style, but I do have a few complaints,
firstly, there is no sound at all (maybe it's just the browser version but still)
secondly, after 5-10 minutes of playing, the game runs at 2 fps (but maybe this is just a problem at my part or it's just like that in the browser version)
thirdly, I want you to add the ability to win or a win screen to appear (since it gets boring after a while if it's just endless)
fourthly, there is no shovel, which would be pretty useful to have.
Fifthly, I noticed that you removed Chomper from the game, can you tell me why?
and Finally, there is no pause menu or ability to restart without having to completely exit the game.
so those were my complaints but don't take them to heart, I just want the best for this game, also I would like to see more levels for this game.
