Competition Entry

This was a competition entry in 2018

You arrive at your red-panda farm, only to find that a pack of snow leopards have broken into your paddock and are going after your flock.

You must build fences to protect your livestock before they get gobbled up:

10 points for the first wah in a fenced-off area
20 points for additional wah, as a breeding-bonus

To build a fence simply press button number one while attempting to move into a paddock.

Once you've separated the species, you'll move on to the next field, with even more leopards. You'll need to save at least one red panda per round to progress.

Some technical details:

This game generates a bitmap using a two-bit palette. The tiles are repeated for the top and bottom halves of the screen, one half using the background palette, and the other half using the sprite palette. This allows arbitrary pixels to be drawn to, at the cost of limiting the number of on-screen colours.
Three of the possible four colours are selected for the bitmap, which leaves seven spaces in the sprite-palette for unique colours in sprites.
The game is developed in C with devkitSMS and sdcc (such a buggy compiler!)

Known bugs and incomplete features:

Animals hitting an incomplete fence should cause some kind of penalty, but this is not yet implemented.
Connecting your incomplete fence to itself should cause some kind of penalty, but this is not yet implemented. This can currently trigger buggy area-filling behaviour.
When shading a solved area, sometimes a line may be missed
As more animals and fences are added to the screen, things can slow down quite a bit
When an area is filled, the fill will cover up part of the fence at the bottom
No sound yet

Changes in R2:

Dead wah are no-longer counted when deciding to fill-in a paddock or not
The text "GAME OVER" will blink above your score when the game ends
When filling a paddock, every line is filled rather than only every second line. (I've improved the line-filling speed, so was able to remove the every-second-line hack)
