Glo Flo is a bit too casual for its own good. If you like puzzle games but generally find them frustrating, this could be a great little time waster. But if you're looking for a mind-bending challenge, you probably won't find one here.
It's not perfect, and when compared to those other games I mentioned earlier in the review, it simply can't compete on that level. But as a short distraction with no pressure of long lasting appeal Glo Flo can certainly fit the bill.
