If you see any weird blue lines on your screen, press the Green Flag again & they'll be gone Please make sure to click the green flag more that once or else it will not run properly. If you need help: for the 1st one (Erosion) spam click untill you get Sediments. Second one (Deposition) use arrow keys to navigate through the river and air. Third one (Lithification) just keep pressing the space bar untill the rock is formed for the Metamorphic rock (Heat & Pressure) keep clicking untill it's at 50 Heat and 25 Pressure and for Igneous just hold your mouse on the Magma. That's about it.
This game is for a school project but uh enjoy :)
