Hey! Thanks for playing the game!
I'm not sure what you mean by point 1 and point 3. Could you explain further?
For point 2 and 4, this is in the backlog of things I want to add to the game.
1. I meas that you can convert the white icon in graphic like a block that you use inside the game
4. Add a dart or some effects to distinguished the starts points and the exits points
;)
