Thank you for playing! There are a couple of ways to win the battles - one way is to talk to the first bug you encounter, and you can get them to join you! You will then have another companion to help you :). Another way is to make the most of your spells and movement during the battle. I like to get just close enough to be able to use my spell (click on the spell icon) and blast the bug with a solar bolt! When you run out of mana, the mace comes in handy (equip by clicking on the mace icon). You can also reduce the difficulty in the settings.
The battles should get more difficult as you progress, so it always helps to recruit more companions and spend your attribute points to level up your character.
Thanks again for giving the game a try!
