Can reach level 15

I watched ads to collect materials, exchanged gems for coins instead of gacha, leveled up weapons, focused on the firepower and defense trees in the combat tree, and chose speed-related skills. I was able to reach level 15 smoothly. However, from level 10 onwards, surprise attacks increased, and if I got touched even a little when surrounded, my hearts decreased. Enemies also have debuffs (like spider webs) that make it easier to get stuck. So, I think raising speed and movement speed at lower levels would have helped with evasion.
