Monster Evolution Demon DNA

Monster Evolution Demon DNA is listed here under Arcade. There is no launcher and no install between you and it. Designed around touch input, and comfortable on a small screen. Its tags here are 3d, action, fighting, running, swipe.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
