I will do that in the future, i had a lot more ideas for this game, like resources, asteroids giving resources, upgrades, and even a way for the player to move a little (at least in 4 directions). The problem i had is: The jam starts/end 8PM for me here, and i only had 3 days to work on it (University is eating a lot of my time). And on the last day i only had 6 hours to finish everything and send.
At the end of the year i will see if i expand it a little.
Thanks for the feedback!
