Cute little game, this is the first time I've seen something made in Play Canvas.
As for controls - they were pretty rough. It might just be the camera angle coupled with the rotation, but it was pretty hard to jump towards the camera, when I was coming back from the far end of the ice blocks. I don't think a platformer is the best place for tank controls. I did get a hang of it after a while, but, it was a wild ride.
