Thank you :)
Indeed the asteroid are released to a 90° angle to follow their inertia. It takes a little bit of use to but i found it more realistic & challenging. :)
I agree for the power-ups. it was in my list of features, but I had to put that aside (along with other few features) because of time limitation. Maybe I'll add that after the jam.
True the display ratio is a bit broken when not in fullscreen. ^^ I'll try to fix it.
Thanks a lot for the feedbacks and for the play :)
