Boxiz is a new game from atari2600land.

Release notes:

Here’s my latest game (in a pre-proof-of-concept stage.) Basically what you do is go around the screen getting boxes (which haven’t been implemented yet) and putting them down at the bottom. Once you get down to the bottom, a new box will pop up for you to get. And, of course, there will be an enemy. The movement is kind of like Frogger, only you want to avoid the playfield as it scrolls left or right. This is a test to see if I could get player0 moving correctly (which I did.) I want to make the goal different from Frostbite, though. I got the idea for this game after reading about Zzyzzyx in KLOV.
