Congratulations on the time! We didn't have time to implement a proper ending so the goal is just survival and beating your own score. The bomb item is something we are aware of, we couldn't fix the issue before the deadline sadly, so right now you will have to either not collect the item or be sure you are far enough away from obstacles or enemies when firing
(A little tip: The bomb drops mostly from stones so if you want to avoid it then this might help)
