Great concept but needs to be polished more.
I enjoy the trash sucking ability, but it can be more than that. The combat with the hand is not good for your game, especially when there is no animations or effect to indicate where you hit. I suggest you to use trash cannon or something else to replace it, that may make the game more enjoyable.
Another thing is your level's goal is not clear. I have to remember where the trash is by myself, which is hard and I may lose a single piece of trash then I get stuck. Maybe you can use a meter to show how much trash is there to be collected, or a arrow to show the direction to remaining trash.
Good work!
