I LOVED THIS GAME. Scored 44k , current top score as of posting!
One thing is that during one of my high scores, the scoring system crashed and it didn't keep my score :(.
I aimed for the highest score to just listen to that song as much as possible. If this was a song showcase, you crushed it.
5/5 creativity enjoyment and audio.
To avoid spoilers I think one of your ratios is off. I like that certain pieces are harder to place, and there's definitely a trick with the environment!
Took me a while to figure out all the mechanics and I was rewarded.
Best of luck to all the other astronauteers! See you in 10 seconds.
