I have ideas for more event floors (such as bathroom and ice rink) as well as a concept idea for building/floor/character modifiers (such as the floor is lava, which makes it so random stuff is scattered on the floor and touching the floor does damage to you, and random upgrades) plus an idea for abilities other than slow-mo (such as rage toss, which makes you toss a random nearby enemy/object and things you toss can have varying effects depending on what you throw.
