Versions comment:
I've uploaded 3 different versions, but they are all basically the same content-wise. Here are the minor differences between the versions:
The first upload (Line Kid.zip) is just to show I've uploaded on time. This one is in the linear color space which has better looking colors.
The other version (Line Kid SofterSFX) has one player hurt sound removed, since it was slightly higher pitched it didn't feel right to me. The SFX is also slightly softer. This one is also in the linear color space. I'd recommend this one because I tuned the SFX to be slightly better, but they are practically the same.
The WebGL build is the only one built in the Gamma color space, that was so it could be built in WebGL. The coloring is not as nice, but it is very slight anyways. This one has the same SFX settings as SofterSFX.
