You didn't sound negative. Your recommendations are really on point!
I think I need to tweak more the deceleration value to make the player be less slippery, but about "why always hold V" it's because on some advanced levels you need to let go the V to be able to manage well the light bulb special ability.
I'm planning to keep the music looping as you told me.
But in terms of the light bulb mechanic of holding it, it's really necessary to stay like that because of the following light bulbs abilities, that depend of if you hold it or not, and its decisive on the levels completion or not, but this mechanic it's explored on the 10 last levels.
Thank u so much for playing my game and for giving me feedback! :D, I'm happy you liked it.
Also, I'M HAPPY YOU GOT TO THE FAST LEVELS hahaha not a lot of people get there :)
