Are Battle Sprites supposed to gain like 1/100 of their heat level meter every depth?
I got the collected heat meter in the top left corner to look like it was full (I know it doesnt actually get full), and when I got on the lift, the level meter from 25 to 26 rose about 3 pixels.
Are sprites supposed to level this slow from heat, or is it a visual glitch, or something?
Long Answer: You need to feed your Sprite materials or Sprite Food, as that's the fastest way to give it heat. The heat gained during levels is minimal to say the least.
