Endearing artstyle! I especially like the way the sun is animated and how the spikes are colored pencils. I couldn't progress past the third level because charging into the wall causes me to fall to the spikes.
I thought it was really great level design! I think it is unintuitive that you have to get the hearts to see your energy and progress, but once I realized I had to collect them the gameplay was smooth. Having the time constraint of the floor rising makes the mechanic of waiting to charge up interesting. I also like how you made jumping consume extra energy.
Very cool charge sound. The controls were a bit confusing (I wasn't sure how exactly how the Bulls/Formation/Grazed differed). Also I liked how you could choose different formation for your cows at the beginning and the death screen is cute!
