Some nice gameplay variety on display here.
I like the progression of the story and the fact that adapting to new controls as the player kinda reflects how the next animal has to adapt to its environement every time you move to the next stage of evolution.
The music is nice and chill, and the pixel art is beautiful, and the little pannel cutscenes were also a very nice detail.
My main gripe is that the controls feel a bit floaty, this proved quite challenging for the start with the jellyfish, and near the end with the fox when you have to perform the jump resets after hitting an enemy.
Other than that it's a cool game, the theme is well implemented, and like i said i like the variety on offer here.
Good job :)
