Keyhole Chasm

A simple platforming prototype I put together over the course of a week or so while trying to learn GMS2. Lots of things unfinished here (no attacking to the left, platforms that should move/be one-way are not, etc,) but go ahead and give it a go and let me know what you all think!
Everything in this prototype belongs to and was created by me with the exception of the ET player sprite. That is simply a placeholder until I create my own. Music, SFX, and all other graphics are my own.

Also I have no idea why there's a second player character in the final room.  I'll fix it as soon as I figure out how.
