Move with WASD, ride Steve the Dodo with R and press E to get off. Collect 2 sticks and 1 stone to make a spear. Craft it by dragging your mouse onto the blinking red square in the top right corner. Move it by clicking on the screen. Go in the sun to fight the boss. Kill the final boss by stabbing it with your spear when it's your turn.
Thanks to @Squidjam for being super fresh. I will probably not add anything to this game, it's just a time-filler.
