Hey, thanks for the great feedback!
I'm glad you liked the concept, our main goal was to come up with something original that also fit the theme well. It's good to see that that translated :)
The visible motions is also a great idea and something we were looking to implement . We had a few sprites for this ready to go, but unfortunately by the end we were rushing a bit to make the deadline and didn't get round to putting them in. This was out first Jam and working under such a short deadline was definitely a bit of a learning curve for us!
Regarding the outlines, we initially planned to have a few more levels and/or perhaps even a boss fight of some sort, but again we ran out of time. For these we were looking at increasing the difficulty by both speeding up the ship and putting the objects closer together. The idea behind the outlines was to be a quick visual guide in situtations where you didn't have much time to react, but I agree that these werent particularly necessary for the two levels we actually managed to get down. I can see why the description may have been confusing too!
Thanks again for taking the time to play and rate the game. We hope you enjoyed it :)
