thank you so much! I had planned to do something that would indicate when the player reached the maximum speed at which the spikes are activated, however, time was not enough for me to do it. I also thought to do something to teach to the player to the first mechanics (I tried to do that in the first part of the level) but I was missing something more graphic, again, because of time. Thank you very much for your comment, if I continue developing the game, I will take into consideration the speedometer :D
