Woah, what incredible visuals! :o The pixel art is clean, tons of effect and feed-back, juiciness everywhere… Impressive work!
And the game concept is pretty unique and fun too! I love the minimalism of its design. It's quickly satisfying and challenging. Perhaps a bit too much on floor 3, the stun zone provided some unfair situations for me. There was some points were I was just desperately re-rolling in vain. Or maybe I wish I could have restarted from the current floor? Each fight is short anyway, so it's not too bothering to retry. And there's enough variety of enemies to make the game fun to play again.
A really incredible entry. A great idea, with very good execution!
