The game jam was originally a single work day jam with modelers new to git and Unity.  Most of the day wasn't spent on game development, but rather spent on introductions to git and getting models into Unity.  It was a good introduction and if we did it again with the same crew then things would be wildly different.

Day 1 saw the ships and firing mechanic into the game.  Day 2 saw the addition of ships being able to fire back with correct trajectories and assignable accuracy.  Day 3 saw ship spawning.  Then there were some tweaks and polishing to round off the game nicely.  Counting the total amount of time that went into the project is tricky.  A lot of time has been spent brainstorming about another version... you could call it version 2.  The actual time spent on this project as it is was less than 48 hours.

The game was originally targeted toward mobile devices in portrait aspect ratio which has been kept here in the web player.  This seems to be a bit surprising to see on a webpage but that's why it's there.

Screenshots and images were improved, the last ship the Man-o-War was added, and the health crate's collider was enlarged to make it a bit easier to hit.  Spawn chance was adjusted on the ships as well, so the more difficult ships are proportionally less likely to spawn, and the easier ships will spawn more often.  We have a theory that this might improve the play feel, but it's only a theory.

Depending on interest, this idea may be taken to use in another project which would be a more fleshed out mobile version.  Complete with world map to progress through levels (Mario style), ship component upgrades, ship purchasing, and special powerups like homing missiles or ice balls.
