Pretty intersting precision game, and it kept my rage level just low enough to power through it, which is a pretty impressive accomplishment. I have a few gripes with the controls, though:
1. Why toggle instead of hold? It just feels so much less intuitive and precise. If you wanted to go for an intentionally "bad" control scheme, I feel like it would have been better to go all the way and have something like a visual console board on screen with buttons that have to be pressed with your mouse. Yes, that would be even more frustrating, but it would be clear that that's the point of it and stuff like that can work for some games, see QWOP for example. This way, I just wasn't sure if the controls were meant to be frustrating or if they were just frustrating due to questionable design choices.
2. There's this weird effect that the rotational motion needs a little time to come to a stop when you stop firing a side rocket, but it immediately stops when you start firing the second side rocket instead. Which leads to the weird effect that it was much easier for me to turn by turning off the rocket I didn't need, which inverted the control scheme, but still felt better than the alternative. Also, I know this is a video game and it's often a good idea to put gameplay over accurate physics, but firing both side rockets at the same time and not moving just felt weird.
Sorry if all this complaining seems like I disliked the game. That's absolutely not the case. As I said, i had enough fun with it to work my way through all the levels. I just think the controls need a little more work.
