2D shooter-revised

This revised 2d shooter includes modifications from the last one. There is now just one level where enemies continuously spawn and the player gets one life. The enemies also spawn at a faster rate as time goes on. The UI was slightly adjusted. Also, I tried to implement a bomb feature, but couldn't figure out how to use the imported input system package. Otherwise I would have instantiated a prefab with the push of a button then with a delay destroyed it and  used a physics 2d overlap circle to destroy any nearby enemies as well. Lastly, the player and enemy and player speeds also slightly increase as time goes on.
