Phew, one day of gamedev just ended, here is a little gif of my progress:

I finished to draw the planet, and I began to make three diferent enemies. The first is a ground enemy, an “Heptapus”, who wants to kill you directly. The second is an UFO which brings 3 Heptapuses, and the third is a ship with a laser cannon, his goal is to damage the planet, rather than killing you.
So you will have to concentrate on the ground and on the air to dodge the Heptapuses and kill the spaceships before they destroy the planet.
Now I still have a lot of work for tomorrow, I hope I won’t run out of time. Good night! 😀
