Pretty fun game! Certainly a fun core movement concept that reminds me of foddian/fumblecore games where the whole fun is getting better at the exotic control scheme. The controls are a little wonky to get used to, especially since it doesn't seem to explain anything, but I found myself getting addicted to the gameplay, enjoying the process of getting more efficient with the controls and being able to tackle the more bizarre obstacles like chaining grapple points. Game also had a lot of nice goofy touches (beyond the obvious goofy frog) like skeleton bones in the background pointing the way.
If I were to have any complaints, and I know I'll sound shallow in saying this, it's that the general presentation is very bland. The game's graphics and style give off, if I were to sum it up, a very 'my first Unity game made with a bunch of free assets' to it. The levels are mostly boring rocks, The HUD is lackluster and layered weirdly where some elements overlap when others don't, the game lacks satisfying visual and sound effects for moving around, the tongue HUD remains even after you die, the death effect is a boring white circle (sphere?) and the death text is a bland system font, etc.
And it's not just the graphics either: the game was clunky in other respects, like how there is a weird and overly punishing pit in the first level that sends you all the way back, giving you the awkward choice of killing yourself to respawn where you were before you fell in or venturing all the way back unnecessarily. Also there was no real charming story or objective to the gameplay to keep me interested in progressing. All of these little things just added together to bring the game down a peg: make it seem unfortunately unprofessional. Again, though, the core gameplay is really fun, so if the other side of the game were to pull its weight a bit more, I think it'd be a match made in heaven!
