HOW DO YOU MAKE SO THAT AN ENEMY CAN STILL ATTACK EVEN IF HEROS LEVEL IS HIGHER IN RPG MAKER VX ACE

You just give the monsters a better attack stat in the database. Or give them better skills. You can make skills in the skills menu. But don't make the monsters too strong, that will make your game too hard and not fun to play. Don't give a simple slime 3000 HP, and don't give the demon god 100. Battle test a lot and see what's right for your game. I messed up on this too, and everyone make mistakes. So take my advice and don't release your game until you know everything is balanced. Try sharing your game with your friends and family. Tell them the things that they DIDN'T like. Because you need to know what things in your game is trash and needs improvement. Also don't ask for reviews until you KNOW that the game is 100% complete and balanced.

EXPERT TIP:
Lower the gold cost of the healing items in the database. It will save players a lot of time and effort. What I do in every new game that I am making right now is that I lower to normal potion cost to 10 so they are actually affordable.
