Opinion on this level upgrading system?

Uhh there's not much details to it, I made this level upgrading system, and I was just wondering what the community thinks of it!

Btw this was made in visual studio with forms. Just because it was easier, and I rly just wanted to create a level upgrading system.

And just so it's clear. That double "experience", would be the necessary experience to upgrade to the next level.

 public partial class Form1 : Form
     {
         // todas as variáveis / All variables
         int level = 0;
         double health = 100, baseHealth = 100;
         double damage = 30, baseDamage = 30;
         double experience = 1000, baseExperience = 1000;
 
         double healthGap = 10;
         double damageGap = 5;
         double experienceGap = 50;
 
         double exponentialHealthGrowth = 1.5;
         double exponentialDamageGrowth = 1;
         double exponentialExperienceGrowth = 1;
 
         /// NAO INTERESSA AQUI
         public Form1()
         {
             InitializeComponent();
 
             levelLbl.Text = "Level: " + level.ToString();
         }
 
         /// NAO INTERESSA AQUI // This was a btn that ups one level
         private void up1Btn_Click(object sender, EventArgs e)
         {
             level++;
             updateLevel();
         }
         /// NAO INTERESSA AQUI // This was a btn that downs one level
         private void less1Btn_Click(object sender, EventArgs e)
         {
             level--;
             updateLevel();
         }
         /// NAO INTERESSA AQUI // This was a btn that sets a level. Used a textbox for this one
         private void setLvlBtn_Click(object sender, EventArgs e)
         {
             level = Convert.ToInt32(setLevelTxt.Text);
             updateLevel();
         }
 
         /// <summary>
         /// IMPORTANTE HERE
         /// </summary>
         void updateLevel()
         {
             // Velocidade em que os stats do player evoluiem / Velocity in which player stats evolve
             exponentialHealthGrowth = 1.1;
             exponentialDamageGrowth = 1.07;
             exponentialExperienceGrowth = 1.05;
 
             // aumenta todos os valores da gap entre os níveis / calculates the new gap diference between the levels
             expectedLbl.Text = "Expected: " + (healthGap = baseHealth + Math.Round(Math.Pow(exponentialHealthGrowth, level - 1))) + " / " + Math.Round((experienceGap = baseExperience + Math.Pow(exponentialExperienceGrowth, level - 1))) + " / " + Math.Round((damageGap = baseDamage + Math.Pow(exponentialDamageGrowth, level - 1)));
 
             levelLbl.Text = "Level: " + level.ToString();
 
             // reseta todos os atributos / resets all stats to level 1
             health = 100;
             damage = 30;
             experience = 100;
 
             // Vai adicionando os atributos novamente para ter uma evolução mais fácil e controlável, ou seja passa por cada nível / Adds all levels one by one, since im using this "gap system"
             for(int i = 0; i < level; i++)
             {
                 healthLbl.Text = "Health: " + Math.Round((health += healthGap));
                 experienceLbl.Text = "Experience: " + Math.Round((experience += experienceGap));
                 damageLbl.Text = "Damage: " + Math.Round((damage += damageGap));
             }
         }
     }

Results:

• Level 10 - health: 1120 | experience: 10116 | damage: 348

• Level 20 - health: 2200 | experience: 20151 | damage: 702
