This is a really cool and creative mechanic idea!
The physics are a bit janky, but I know how painful and time consuming these things can be to fix sometimes. Also, I was a bit confused by having to click two times, every time I wanted to start over, but that's such a minor detail, that it shouldn't have an impact on any rating or the fun I had while playing it!
So overall like ScarfRavenStudios already said it could need a bit more time, but it's still a really fun game idea!
