A to jab. D to cross. SPACE to block to regain health. When you win wait a little for the stats to show up. If it doesn't, click flag. The reason why that happens is because when you KO the dude and you were at low health, the project will detect you winning, but then the guy keeps punching and then eventually KO's you so then the project detects you losing, Therefore clicking the flag again your at full health so you get to see the stats.
This is a side project and the free roam game ive been talking about will be uploaded. Also this game is kinda like wii boxing.
