End of Day 1 ! ”Going Deeper!”

GOOOO, the jam starts and the theme is "Going Deeper!

Aaaand...the first day is already over for me, after ~3-4 hours of work! Unfortunately I have to work tomorrow, so I didn't get much done today.

So what did I do today? I started thinking about an idea and found one that I like.

The idea is to make an endless runner, but vertically, so you basically fall! Some elements and enemies will try to stop you! Will you be able to reach the end?

Oh, and I'm thinking of adding some bosses and lots of cool stuff. Have I already gone too far?
