Cave Rocket is a simple gravity based simulator. You control a small ship to fly through the procedurally generated caves. The more you advance - the more difficult the caves become. Once you finish the last level you can infinitely continue your journey while next caves becoming longer and longer, but to compensate that you'll be awarded additional lives from time to time.
I started to dive into gamedev not long ago (though I have pretty much of experience in other development spheres), and this is my first ever game, which was started mostly as an exercise in Game Maker Studio 2. But since most of my friends liked it pretty much, I decided to submit it to itch. Hope you also enjoy it :) And find it challenging enough.
