A few fixes

I made a small update to address a few things :

• Update to the enemies death creams, with a few changes and volume tweaks (thanks St. GOGO as always) 
• I noticed that the game was getting too easy after the last cards I introduced, so I decreased the starting SP from 4 to 3. I may revert this decision in the future. 

I probably won't be able to do any major updates until the second half of April, because I have an incoming wedding ceremony (mine :P)
