We always talk about doing a "Lick" mechanic like this for some Overcooked style game. It was nice to see an interesting platformer. I was a fool and first I could just use WASD to begin with, and only on level 3 I realised I can move with arrow keys! It worked well, I liked how the movement ended up progressing. I did end up getting stuck though on the last level!
Finally, launching your tongue at ice is DANGEROUS! Thankfully this frogs tongue was not vulnerable to the dangers we face!
