Yes, Flash lives on!
Despite finding the game a bit boring (not everything is for everyone, and the game is what it is) I would like feedback on the tutorial. You said you didn't understand it? If so, where did you got stuck? And at what point you started understanding the game?
I experimented with Keyboard controls but whenever I press a Key for Next Frame, if there are many "Next Frames", it just plays the entire timeline until you stop holding the Key down. So, I don't know how to do that, as much as I would love to.
Edit: I just found a way to fix this! Whoo!
