A very simple 2D cavern-crawling arcade game!

I like that you get to figure things out as you play, and this game does get me to be a bit cautious of my use of light-orbs after some deaths.

The game certainly never ends until you want to (arcade games do that, right? Am I wrong?), so I had to stop once the number of dots indicating the area-lighting orb upgrade costs begin to overlap with other graphics. It's amusing to see.

So if I wanted to play for a short spell, this is certainly some of those games I'm replaying.
