I summoned a demon inside a cathedral and now its collapsing

My entry for olcCodeJam2019. Written in c++ (self-taught n00b).  I used javidx9's  olcPixelGameEngine for windowing, keyboard input, and handling PNGs.

I had to move apartments over the first weekend so I didn't get much time to work on it, but am submitting what I was able to get done. The idea is that you summoned a demon inside an abandoned cathedral, which has caused it to come crumbling down. You must escape through the top of the cathedral, by jumping from falling stonework.

CONTROLS:

arrow keys - move left and right

spacebar - jump

R - restart game

**I wrote this on a mac. I made a windows build, hopefully it will work because I know pretty much everyone else is on windows.
