I only wish mobile makers would get serious about increasing battery life, because as soon as you load CPU/GPU on these devices, they got flat real fast. It's more like they are made for idling rather than serious gaming.
Besides that, C2 + Mobiles & PC = great currently!
The "New Game, Continue" are blurry sprites I made on purpose, on PC it fades out after a few seconds of inactivity so the background battles come into play and it becomes like a stress test / screen saver.
I ran it on a Galaxy Tab A (1024 x 768 resolution), which has terrible hardware and it was running really smooth! But I was hesitant to recommend it, knowing that there's so many older Android devices which can have issues with Chromium.
