That lake before snowwy? (Urgh, robby
) It's serves as a diving pool to me...I usually zap a few yetis to chill with me then I have a party. What I do want to suggest is, gravity, or harder to move areas because of the effect of an area. So say, I think in Snowwy Flats, when you're in the lake, your health decreases as you stay in the lake for too long. Slowly, unless you have freeze resist armor, which could go with Naruto's Cryo Armors or something easier, like Lvl 1 items.
I also would suggest slower moving in Wastelands...Maybe because of the darkness surrounding the area is so evil it pushes gravity down, and so that it's slightly slower to move. So overall I'm suggesting moving due to area moods, so for new players it's not as hard to play.
One more thing; we need some more floor hazards with different elements, I can see most of them now are nature based, we could try some fire in a volcano map, some freeze in Snowwy, Shock in Robo, and Poison in Carnelia based places.
