simple but effective. The only probleme i have is, fly spawn too much out of reach at the top, and a lack of explanation about the health meter, it seems the stress work the same as damage like a time limit but is inconsistent, i couldn't really grasp how it work/increase. And also hard to see when poison decrease your lb. I would increase the scale of the frog as he gain/lose wheight to have visual feedback and satisfying result for playing good. I still had a good time playing this.
