No, I think I understand what you mean. Unlike other straight-forward one-button games, this one requires a bit more thinking and planning as you play. When I plaaytest my game to get a high score I have this general strategy that I follow. Essentially we want to move as much as we can while being as safe as possible. So I'm always pressing the button whenever the opportunity arises I also need to pay close attention for when I'm in a pinch and spam to get out of the way. Sometimes it works, and sometimes it doesn't. And when it doesn't, I know I can always try again quickly to try to achieve the dream run.
Having two random buttons sound nice, but also difficult to implement with the chaos. The spaceship faces the direction it's going to go, so if it instead has two direction that it can go, it's not possible to clearly indicate that based on ship rotation alone. If I include an alternative hinting, like an arrow on the top right of the space ship that is the same color as the alt-button, it could work. But I think it'll be more confusing for new players. Worth a shot though.
Thank you for your feedback Marxy! Glad you liked it :D
