Hi, I try to write there some my ideas, what we can upgrade in this awesome game.
When monsters spawns in zone why don't do some graphic's effects like opening portal from where monster spawn? I understand, that's not very important, but this detail changes reality of game. Spawn monster type can be "from where" mobs spawns. Example, Devil's can open portal from hell, Angels can open portal from heaven or clouds, let's try to imagine, that monster opens portal, dashes screen, and jumps to zone in 1-2s. animation. When he dashes screen, opens portal, we can see some beautiful background
