Oh my goodness I made a game really similar to this when I was 14 except it was a platformer, I love it!! Such a cute character and concept and a great way to approach the count down as being life. I love how revives are part of the gameplay and for me I didn't mind backtracking too much. It seems a lot of the suggestions I have were emphasized in previous comments, mostly for me being confused what was considered interactable/collectable and what wasn't initially until I played the game a bit more. But there's lots you can do with this post jam, you've made something very very lovely!
I love your little blob character, I have a few game characters that are just blobs too
