[1.2] More levels and Q.O.L !

Hello everyone !

After some times, I reworked a little bit Sankeductor to fix some minor errors, as well as some more important Quality Of Life concepts involving gameplay, remaping inputs, having a reminding of the controls, saving informations on levels done...
It was also the occasion to add more levels ! Now the mechanics are a little bit more dilated across the 24 levels, and in an order that suits the way I wanted to convey they.

For now, I will stop a little bit the progress on Snakeductor (except issues that makes the game not function), I'm happy with how I iterated on the mechanics but I may try other things. I may return to it later but for now I'm preseting you this version that encapsulates the gameplay I wanted to provide with Snakeductor.

Hope that you'll be having fun with the game, and I'll see you next time ! (For a new project maybe !)
