Try to defeat the other player by pressing your button with good timing. Player 1 uses W as their button. Player 2 uses I (i, not L) as their button. The game goes through 2 phases. In phase 1, both players aim their weapon and decide how hard they want to fire. Press your button when your turret is aimed in the right direction, and then press it again when your Power variable on the top of the screen is at the power level you want (it may take some getting used to). Phase 2 starts after the "ready..." message. Focus, and press your button when you see the "FIRE!" message, no sooner, and try to fire before your opponent to win.
This is my second original tank game, hooray! Another tank themed game of mine, but with a lot more work: https://scratch.mit.edu/projects/803417486/ This game took some inspiration from this one: https://scratch.mit.edu/projects/80322642/
