Swinging the space ship feels like swinging a medieval flail, just in the future, i guess?! The game was very fun and am amazed that you implemented different game styles.
The ultimate is the most fun. Unfortunately, i couldn't fill the bar that often, i usually died first. Perhaps you could also let the bar fill over time. This way, you could also reward player's who play bad.
Apart from that, i enjoyed your game. Great work.
