Wow, very creative and definetly fits the theme :D, some of the levels were really difficult, and that final level took me some time, but very good. Only thing I would say as advice is probably, focus you artistic skills and time more evenly, because the trees in the background are beautiful, but then you have flat spikes and a slime that doesnt have much detail, so its better to have a mediocre background with a mediocre slime and mediocre spikes than a great background, meh spikes and meh slime, it makes the game looks less coherent. I finished the game with 70 deaths.
Solid entry 4/5.
