This was an interesting game idea. It would have been nice to have some idea of the controls and what to do. Initially I pressed a bunch of buttons and found the space allowed jump, and the left mouse shot out the frog's tongue, but did not see it doing anything. It took a bit before I noticed the mouse position affected the jumping direction. Eventually I figured out that the tongue could be used to swing, and wall climb, if used while jumping. Later I found some text that explained this, but only after I had climbed up a ways. That kind of text would be helpful at the start. I hopped around a bit, but with no direction or idea of the goals I did not get far.

I did hear some audio comments being made after I did jumps, but it was commentary on how you did, such as "Wow, that was almost impressive", and only after I had done bigger jumps. I did not hear any kind of instructions at the start, nor as I progressed telling me in advance how to do things.
I understand running out of time for in game instructions, but you can add them to the web page for the game. Uploads are locked during voting, but editing your page is not, so you could still update it to help others who play.
