Nice one! I like the shift from collecting trash to saving animals and how you then need to avoid the trash to not waste time. The colors look really nice on the sprites and make them come to life which is essentially why you feel that you really wan to save these creatures haha
I think a little more variation or something fighting with your hook could add a little more variety to the game if you expand on it afterwards. And also fast forward the timer for the last 5-10s, because there is not enough space to save anything :(
Really enjoyed playing this one, good job!
