Fun and addicting! 

While the premise of the game is simple and there aren't much variety in the dangers and mechanics it's still so fun that you don't care. It's challenging and you probably will die before reaching even 5 floors but you re-spawn quick enough that it doesn't become frustrating.

The pixel art on display is good but the style makes it all come together perfectly.

The music is very good. The menu music is very calm and ominous  while the main theme has good rhythm and is constantly motivating you to to go further.

I would absolutely recommend this game.
