Thank you! I'm used to use the pixel perfect component in the unity to make the sprites keep their relative sizes in relation to the screen, in addition to that I almost aways make games that uses only one screen levels, so when I made the sprites I completely forgot that this game in could have bigger sprites, and would be better if it had hahahah I only saw that when I was with all animations of the main character and the enemy made, and I was like "this is too small, but its to late now to redo all this D: " I totally have to pay more attention on this things in the next project hahahaha.
