TAP GALAXY is a space mining incremental clicker game where you mine exotic planets, moons, asteroids, and comets for resources that help you colonize galaxies and build your Galactic Empire! The game starts on a small, moon-like planet that you can tap on to collect resources. You can then spend what you've found on new miners, machines and boosts– and that's just the beginning! With the help of Colonel Flint (who's much more than an ordinary chimpanzee), you can explore your Galaxy and search for new resources to mine! Reach the farthest corners of the universe by buying space probes and leveling them up. The galaxy is yours to explore! But wait, there's more! Wormholes will let you move from galaxy to galaxy where you will discover uncharted planets and resource rich moons! Who knows, maybe one day you will be able to conquer Trappist-1! But be careful! The universe holds ugly surprises as well. You will have to defend your ground from terrible aliens. Don't let them stop you on your intergalactic quest! Start mining now to grow your Main Colony... turn it into the largest in the universe! The potential is endless!
