I love the idea of a blob evolving to be more plant-like or more animal-like (or both!). The way the player chooses which path to evolve down feels a bit strange, particularly with the buttons appearing while you can still move. However, I think I see the idea of gathering sunlight to get plant abilities and catching animals to get plant abilities. That's a really solid idea.
I also managed to get across the water after several tries. It seems to be a matter of how far away you are when you dash at it? I'm glad to I got to see the end of your game! Really well done!
