Kinda cool, I'd give it a 5/5 if the art it made would actually not look like clumped up things and actually more art.
If less things spawned in the same area it would be mucch better.
4/5
Just great. Like you said, completely simple but extremely compelling to play. If I were you I would make another game, name it simplicity v2 and add in new effects. Such as: Achievements, possible upgrades, different gameplay styles, different graphics, and so on.
I hate the people that are flagging it for not being a game. It's close enough to be a game. He customised it and spent time on this. It's an amazing idea if you want to watch a video and chat at the same time or save a video or playlist and watch it later. 5/5 faved. Please do not remove this gadget.
