Double jump
As a super early X-mas gift (or perhaps a late Thanksgiving gift), I present to you the double jump.

What it does: Makes it so that space jump will only give you 1 extra jump, like the Prime series. Additional code was added so that if you want, screw attack will give you 5 extra jumps like MP2 (you just have to comment out 1 line and uncomment 2 lines).

Be sure to find your freespace in $90 first.
