I've played this game over and over, I was really addicted. What about you? From Nobstudios, here's Hell Tour. You'll get the hang of it.

I couldn't beat 2.

Stuck on like 8

I'm stuck on 16, too hard. Enemies with like 500 soul keep blocking me.

EDIT: I finished ALL 19 levels, but at the 20th level, there is something called "Mr. Devil" which I've to beat, and I couldn't beat.

Spoiler:

Same thing as Dream.
Fun game.

You need to max out at least one of your stats to beat the game, if you can max out all of it, you can probably take over the devil.

I know that, but I added 3 of mine to attack, 3 to soul, I could max Soul if I added all 6. I thought I had to fight against that devil, and not like that story. xD
