When Compiling to WebGL, not all Sprites Render Properly. Why?

I've made some updates to a game I made for Ludum Dare 34. It was working perfectly fine in the first release, the graphics looked as intended. After making a few changes and recompiling for WebGL, the player sprite and power up sprites are all showing up as black blobs. You can see what I mean here: http://bazkur.itch.io/stickman-sam-in-the-high-fly-sky?secret=zMzoOTZzeccZC0uvl0wr9V1kMeY I've not changed any compile settings from the last compile and the game runs perfectly fine as an executable. Any idea what would cause my sprites to look this way in WebGL especially considering it wasn't an issue before? Thanks!
