What is the name of a very old computer game?

What's the name of this old computer game?

• So I don't remember a lot about it because I was little when I played it. So if anyone can help me out that would be be great. The things I remember might be a mixed up. But if you do have any idea what game it might be please let me know. So this is what I remember. I think there where a cat & mouse but I may be wrong I think one of them was blue. I don't remember what the object of the game was. So anyway the screen was blank and you hand to work with all these objects such as bouncy ball, you could make a a pulling system using strings and those pulley wheels. I think there some kind of bomb or grenade or something. I believe there where balloons. and there where platforms like metal, and wood etc.. and there was a bunch more other stuff. You could place this stuff anywhere on he screen then you would press I think it was the action button and they all would move. If there was no platform at the bottom of the screen then most of the stuff would just disappear off the screen. So I hope there's someone out there that knows what game I'm talking about. Thanks.
