Very fun game! The art style is very colourful and blocky which is nice. The controls feel like a challenge to manage but also very simple which makes it fun to play. The oxygen bar is slightly confusing as it is blue like the cobolt, maybe it should be white? Sometimes no asteroids of the colour you need pass you and fuel runs out very fast so you just have to wait for asteroids (maybe have more asteroids or decrease fuel consumption) The highscore feature is cool and it is fun trying to beat old highscores. When you run out of fuel you are stuck floating in space, maybe you could leave your ship to mine green asteroids but have extremly low health. Sorry for overloading with ideas, I am excited to see future developments! Good Luck!
