How to play

On Desktop Left and Right arrows rotate the cannon. Up and Down arrows increase and decrease the strenght of the projectile. SpaceBar shoots.

On Mobile Touch and drag up and down on the right side of the screen will rotate the cannon. Touch and drag up and down on the left side of the screen will adjust the strength. Tap the screen will shoot.

Seems like it might be broken on iphone (safari)?

It’s placing two tanks on a blank background directly next to each other every match, and it’s trivially won every match by just ramping up strength and not touching angle (so it just shoots straight at 0 degrees).

It’s difficult not to win on the first shot

The game (probably because it's a PoC) uses the width of your display window as the width of the game, instead of a display independent width. So if you have a narrower window, the tanks will be closer.

In the narrow confines of a smartphone this means the tanks are right next to each other.

Rotate phone to landscape and refresh. Much more playable.

It behaves randomly on ios safari, tried portrait and album mode. Tapping to shoot works, but when you drag, vertically, horizontally, otherwise, it either does nothing, or lowers the strength to zero, or turns the cannon either exactly to the left or to the sky.

By album mode do you mean landscape? I've never heard it called album mode before.

Yeah, landscape. It was translated to my language (russian) as “album orientation” long ago in winword and I make this mistake from time to time. Portrait sounds like “book-ish orientation” btw. I believe that’s because books are usually portrait-like and albums tend to have wider pages. https://www.google.ru/search?q=%D0%B0%D0%BB%D1%8C%D0%B1%D0%B...
