Love the concept of the endless swimmer! Perfect simple mechanic of a typing test to keep your character going. The animation speed being tied to the swim speed is a great touch. Being able to actively collect the yellow dots to have speed boosts or similar could really make this an interesting skill challenge as well. I noticed that it becomes much more difficult to try to hit space to dive down for the yellow dots while typing. For me, I think when I'm typing, I expect the space bar to be in between words, but when i have to push space in between random characters, it breaks my lizard brain. Great work!
