Interestingly enough I actually thought of that exact idea about shrinking the hitbox when I was playing another game from this jam, and I encountered that exact problem. I'll be sure to use that next time I make a game similar to this one.
I had never actually heard of Faster Than Light until I read this comment, but after looking up the soundtrack I can see what you mean - the music does have a very similar style. My main inspiration, at least for one of the songs, was the song "Robot Waiting Room #4" from the Portal 2 OST.
Thanks a lot for your comment! I'm glad you enjoyed the game.
