Thanks for the honest feedback!
yeah i am aware of all the problems you have mentioned, i tried to fix everything and make longer music but i am not an expert in audio just to find the right program took me one day about the jump i and some of my friends got used to it pretty fast so i left it as it about the levels they are generated randomlly so i think that is the reason and about the flying ships i found it very difficult if you die when you collide with it so i decided to make without any damage
Thanks again i really appreciate your feedback!
