Welcome to Just muffins! In this game you are doing most of things with minimal amount of automatical actions. I didn't write the instructions in the game (again) so here they are. Fullscreen is glitchy, play in smallscreen. Double click green flag is probably necessary. Just hold the sugar bag above the bowl for few seconds. Next, drag the butter above the bowl and relase it. Finally, use mixer, when the lamp is green it means its working. With flour and milk you have to do the same as with the sugar. Use the spoon to put baking soda and salt into the bowl. To do it, touch ONE of them with the spoon and drag the spoon into the bowl. Next, do the same with second one. Eggs can make some problems. Get the egg and move it slowly up and down on the edge of bowl. When it cracks, drag it above the bowl, then again int bowl, if it looks like a fried egg, relase it and do the same with second egg. Mix. Select a flavor, put it in the bowl and mix. Touch every empty place with the cake to fill it. Wait. Select the flavor of cream from the list using the numbers 1-6. It's irreversible! You can select a button no cream if you don't want the cream. When you selected the flavor, press space to start decorating the cupcake. Nevermind the floating cream, later it'll become prettier. Do the same with icing and sprinkles. If the sprinkles don't show, don't worry, just keep holding space button. When you finished, use left and right arrow keys to change the backdrop and up and down keys to change the napkin.
