After Jam Changes

I collected your feedback and changed game according to that.

1 - Lower spawn rate of enemies. Now beginner player have more time to get accustomed to controls of the game

2 - Lower speed of rockets. Now they are slower and weaker enemy, but they do get faster over time

3 - lower volume of some sounds so it more bearable to listen to it

4 - Made a restart button at top of the screen work
