Hi Tomato, thank you for your feedback!
The velocity of the enemies is bugged, I think I used the wrong way to do this. In my computer they walk fast, but its use too much ram and I only noticed that after submissions are finished. The intended was to the game have fast battle, but because of this bug it wasnt possible.
Thanks for the suggestion to improve battle, my inicial idea was fast idle battle, because I play some games like that and I like, but I understand that is not so fun.
And its was my third game in Godot, I'm learning each time more, the menu took me a long time to make hahah
