Yep you're right, options were broken, I patched 'em up just half an hour ago. You're also right about the fuel line in the bottom blending up, the ship booster also dims based on the fuel/energy you have, but I don't think it's obvious enough. I'm really glad you enjoyed the game, it's my first time making a game tied to music/sound, it was kind of a mess. :)
Thank you for your review and for playing!
