You are a lone space traveler whose ship has been impaired. Unfortunately, the parts you need to repair your ship have fallen into the black hole, and you have no way to get them out.

Kill dangerous enemies that are trying to kill you, or trick them into being sucked into the black hole. If enough things fall into the black hole, it will violently eject its contents, giving you a chance to recover the ship parts you need.

• Move (WASD)
• Aim (mouse)
• Shoot (left button)
• Grappling hook grab/release (right button)
• Multi-dimensional anchoring boots toggle (spacebar)

• Flame thrower
• Gatling gun
• Gravity well
• Rocket launcher

• Freeze ray
• Laser

• Chainsaw
• Plank with nail

You'll be knocking enemies into the black hole, either by tricking them into the black hole or by killing or otherwise paralyzing them so that they naturally fall into the black hole. Once enough things fall into the black hole, the level ends.

The food cart shows up along a side of the screen from time to time. You can purchase health-restoring food and possibly even weapons and such from it. You spend points (score points), and the prices are somewhat proportional to your score.

• Black hole somewhere on the border that sucks things toward it
• Enemies spawning around the border of the screen. See types of enemies below.

• Style points for killing enemies awesomely
• A certain amount of stuff needs to fall into the black hole

Enemy collision: yes, Starcraft-flying-unit-type collision while the enemies are active; no collision once they are dead.

The typical, basic grunt unit.

Ranged unit that attacks by throwing coins at you.

Relatively neutral unit that appears on a side of the screen, prepares, and then charges across the screen, damaging anything in his path and leaving behind a temporary rainbow bridge that can be utilized to quickly travel across the screen. It may or may not be possible to latch onto one with your grappling hook, and even if it is, the effects may be deadly...

Heavy unit that has a slight gravitational pull and possibly also a large attack that can dangerously launch other enemies at you.

You have two options for contributing:

• Push your branches directly to this repository.
• Push your branches to your own fork.

I'll explain the case where you push directly to this repository:

1. Be a contributor for this repository. Send me a message; I'll add you.

2. Clone this repository. This will automatically set you up with a remote called origin that points here.

3. Delete your local master branch, so that you won't accidentally push to master:

   $ git checkout origin/master
   $ git branch -d master
   

1. Make sure your remote tracking branches (branches named origin/*) are up to date:

   $ git fetch origin
   

2. Start a new feature branch based on origin/master.

   $ git checkout origin/master
   $ git checkout -b newbranchname
   

3. Start coding! Commit often! Don't worry about making too many commits; we can combine them into fewer commits later.

4. If there are new commits on the repository that you want to incorporate into your feature branch, fetch and then rebase:

   $ git fetch origin
   $ git rebase origin/master
   

   If you end up with merge conflicts, run git status and follow the instructions. Keep running git status as you go. It will help you through them.

5. Push your commits to the repository:

   $ git push origin branchname
   

# Display useful status about the current state of your branch
$ git status

# Display the commit log for your branch
$ git log

# Stage changed files
$ git add <file>

# Commit staged changes
$ git commit -m "<commit message>"

# List all branches on your computer
$ git branch -a

# Check out a branch
$ git checkout

# Make a new branch
$ git checkout -b <new branch name> <base branch name>

# Download updates from a remote repository
$ git fetch <remote name>

# Rebase your current branch on top of another branch
# This is most likely what you should do if you have made some commits
# on your branch but there are new commits in the master repository that
# you want to include.
$ git rebase <branch name>
