The green monster in The Green Mission: Inside a Cave needs your help and of course you just have to help him. To do this, you need to go with him a large number of levels, each time fulfilling a certain condition: you need to collect a yellow card, after which the door will open leading to the next level. To move your monster, you will use the arrows on your keyboard. You will also be able to change the color of your character in the game Green Mission: Inside the Cave. This is necessary in order for our monster to interact with blocks of bright color, which will change their color from contact. This is necessary just so that a map appears, without which it is impossible to pass each of the levels. Also in the game there are all kinds of obstacles in the form of hot lava and enemies. You cannot contact any of them and you need to find ways to overcome them. For lava, you will have a bathyscaphe, which is activated with the X key, and you just need to carefully jump over enemies. Also, enemies can be destroyed, for which you need to jump from above directly on their head. Remember, if you die, you will have to complete the level from the very beginning, which at later levels will throw you far back. Try not to let this happen, because it is more interesting to open new missions, where the developers of The Green Mission: Inside a Cave have prepared more interesting adventures for you.
