The controls aren't very intuitive at first, but once you get used to them, they start to make sense (though there is some kind of a bug with multiple directions pressed at once - the game ignores some inputs).
I'm not sure why the hedgehogs eat gree frogs and not red ones and due to controls being a bit tricky, it's extremely hard to beat without losing frogs.
The idea is cool though, could be something pretty fun ;d
