Check it out!  1024 screens!  When I only had 64 screens I added a gimmick to flip screens upside down at random to give the illusion of extra content.  So all these screens in the gif also have flipped counterparts.

My initial barebones game only had run length encoding.  I could only make 16 screens with limited detail.

Then with a chunk palette I could make 64 screens (still in a 4KB rom).

And then with 32KB I had a lot more freedom.

I wanted to highlight a few screens.  Check out my Atari inspired screens:

It's a space game so I had to have some cool space station looking stuff.

Here's a bunch of other screens I think are cool.

When I was a kid I loved biking to swamps and catching all kinds of bizarre creatures, taking them home, and observing them in our outdoor aquarium.  One day I was at the swamp and realized I had forgotten my brother's birthday party!  Whoops!  One of my favourite swamp monsters is the water tiger!  One look at this beast and you know what they're all about - nothing good!

Here's some more swamp critters - water scorpion and juvenile salamander.

While working on "Oh Shoot!" some wasps just moved into our house - lots of them!  1000s?  I admired their tenacity, but they fared poorly against our vacuum cleaner.  I immortalized them in my game.
