Finally cleared Level 15~

Getting the Wind Rifle +3 and properly upgrading it made things a bit easier. If you don't strengthen your bots, weapons, and gear properly, you'll get surrounded by tough enemies with no gaps and it's game over, so if you're free-to-play, you need to put in steady effort lol The Level 20 quest has also appeared, so I'll keep playing. I wonder how long these level quests will keep coming?
