Fighting engine, as you can see. Controls: WAD to move SPACE to attack A or D + SPACE to do special attack S to crouch Z and A or D to boost W and Z to superjump up and down arrow at the same time for reflection block. W+Z+A or D will basically make you fly. If you smash into the ceiling, you could smash your head through. Spam move keys madly with key S to free yourself. If your stamina hits zero, you start to lose health from overwork, so be careful, but you can't die from over exhaustion. Your health will stay at 2. Your health and Stamina will automatically regenerate. The weird red tank thingy is the enemy. Attack with space key to kill. It has 20 lives and will respawn after a while. It cannot fly, so don't worry! Haha lol XD. Tell me in the comments what you want to be added. If you time it perfectly, you can use a phase move to go through the platforms. If you jump right next to a platform, you get an insane jump boost. Also, you can ride the enemy by getting on it and scooting in the direction you want it to go.
From an amazing book called coding games in scratch and a most of it by me! Half of the running mechanics by me and the jumping mechanics from the book.
