Thank you so much for the feedback! When the theme was announced and it was evolution I kind of panicked thinking that I was only going to come up with ideas that were too ambitious in scope and settled on this one. Spore definitely was an inspiration, so I'm glad that's where your mind jumped to.
I wanted to make a clear and defined way to win and lose so that is why I decided on just getting the core dash and at least one enemy in the game first and then worked from there. I had a lot of ideas for other ways to evolve, but I didn't want to get carried away. I felt as though 3 was an okay amount so I could go on to making the title screen, and getting the shaders to work as the eyes orginally did not serve as much of a purpose.
The music and SFXs were very last minute things that I threw in just so it wasn't completely silent. I wanted to come up with some kind of music or background ambiance, but that is not my expertise and I didn't want to include random copyrighted music or anything.
I'm really glad you enjoyed it though!!
