This was a fun puzzle game! My favorite part is how you implemented the whistle as sort of a way to direct the freezelings, just like how whistles in real life are also used for directions. I also think the levels were fairly challenging, and I think the restriction in terms of how much arrows I can use helps with that. One thing that I wasn't sure of though is the background audio that becomes more audible after the music stops looping. There's this crackling noise which was a bit distracting, but overall the game is still fun!
