Hi, your feedback means a lot to me. Thank you ;)
All the issues and the possible improvements on the user experience of the game has been thought during the jam, as well as others like camera shaking and sound distortion near the blackholes, or the blackhole's size to reflect its gravitational strength and radius (which actually differs for all of them). Unfortunately, I simply did not have enough time to do all of that.
I may implements all of the above, once the jam is finished tough.. stay tuned ;)
Thanks again so much for playing it and give your thoughts and feedbacks. I really really appreciated it.
