The video about my videogame idea got positive feedback, so I kept working on the game. I have enough material to create a demo. You can play it on itch.io:
All the instructions are in the demo itself. Just to warn you in advance, the asteroids and the enemies are programmed to spawn on the borders of the camera and they go in random directions, so it's possible that they'll fly off the screen immediately. Unless you want to torture yourself, don’t mash Q or E.
What do you think of the game so far? Does it feel good to play? If you think the demo itself is enjoyable enough, I can put it on my website, so it’s easier to access. Just say the word.
