The concept is hopefully simple, although far from unique. Get to the bottom of the level, avoid the obstacles, and collect the gem. Planning on having a few levels and maybe a backstory that fits with the theme.

So far I have the player character that can move back and forth, stationary obstacles, moving obstacles, walls that merely block your movement, and a gem to collect.

Next up is a simple level select screen I think, and maybe starting on some simple art.
