Light Flow on the Nexus 5

Hi guys,

I was thinking about purchasing Light Flow, but as I was checking out the reviews for it I filtered to only get reviews from Nexus 5 owners, and after doing that the reviews look somewhat bad...

So I was wondering if any of you have experience with it on the N5, is it really that bad on it? Is the dev slow or unresponsive?

I'm probably gonna try the free version but I was still wondering if any of you had some input on the paid one.
