Hey, thanks for the comment!
Due to many complaints about the web version being crashy, I decided to remove it temporarily from the game page. But I left the Windows version still available. After the voting is over, I'll get back and hopefully deal with those nasty crashes. Thank you for notifying me and sorry for the inconveniences!
You can check the procedural animation tutorial I used here. It's pretty easy to implement, actually, and have many different uses (for example, the seaweed is made by using the same technique).
