The 3rd Birthday

[chrisDLCTS]

using version 0.7.5-25
on android.
when I get the the second mission where you start off fighting the worm boss thing, everything runs fine at first. after I best him, I go through the level and make it a few areas in, and then when moving to the last area, I get a black frozen screen while transitioning areas. always happens at the same spot.
