This is perfect
This is really fun, it can be quite challenging, while not frustrating.
I spent almost 2 hours on this, and I can say it was worth it.
But damn, I ignored the thief and he showed up in the second last level and took my gem. I was like "noooooooo"
But great game, none the less.
I really like it.
And as other have said, the music gets annoying after 30 minutes.
