After talking to Gardevoir boss, we need to defeat gardevoirs so the boss can reappear. I defeated all of them, but the boss is nowhere.

Context: This is my 2nd run today. First time I could clear without problem.

Hello @Feki93.

 

Based on the footage, it seems you did not check one spot where Gardevoir can be in. See image below.

Spoiler

Right behind the candlestick, you can see a few pixels poking out. That's the missing Gardevoir that was preventing the boss from spawning. 

I know it may be hard to see, but that's part of the challenge. Try to look more carefully next time.

 

Let me know if you have further questions.

Oh, ok thanks! I didn't expect you hide them this way. 🙂
