Title: The dungeon master is a cat

When he came to, he found himself lying under a tree in a wide meadow. He found himself having a hard time standing on his two feet and can only stand in all four. When he exclaimed, he only heard a "meyow~?!" Sound.

What's this? What is going on? Why can I see a floating rectangular window wherever I set my sight on? I can even still see it after closing my eyes?

A tpa-tap build game?

What's a Dungeon point?

What's this 'Dungeon crystal: Gathers mana in the air and converts them into Dungeon points?

"Merrryeow?! Meeeyyeow!!" Why am I a cat?

The Dungeon master is a cat.
