Heya Philip! This game was super neat and I love how you tied the mechanics, setting, and the button altogether. The trail on the moon and the asteroids were a really nice touch too.
One thing I did notice while playing though is that the player could easily stay in one spot if they kept pressing space over and over again. I personally feel that it shouldn't be possible, but that's just me! It could be a really cool and risky strategy for someone.
Another thing I felt mixed about is how the difficulty ramps up over time. I feel like the game starts off pretty slow, which is good so that the player can learn how the game works, however I didn't feel challenged while playing the game until maybe a minute or two in and I personally feel like this game could work really well if it ramped up a bit earlier. That's all the critique I had, but either way this was a fun game!
