Also another thing about the keyboard is that the numbers work as if they were other keys and the letters are not used to rename the saves or map them in the button configuration menu
I was able to pass the first episode, the boss battle was very slow but not enough to be impossible to finish it and another thing when they pass an episode, they close and open the game so it doesn't crash in the middle of another episode
For the next update they should put x + Up / Down to change elements and also that the music is fully compatible because I only managed to hear the one on the screen when you passed a level
