Jump Gunnar, Jump! is a challenging homebrew platformer for the PSP, with 30 stunning levels.

Installation

Put jumpgunnarjump folder in /PSP/GAME/ directory of your Memory Stick.

User guide

Story

You are Gunnar, as seemingly average every day sheep, with a gun. You can run and jump and well, shoot.

But somehow, you've ended up in the evil Shephard's gauntlet. You need to make it to the end. But it isn't as easy as it looks.

The Shepard has fixed it so that you need to collect 50% of the fruit to leave a level. Work hard, and you can move on.

How to play

The top of the screen is the game status. It tells you your health, lives left, amount of fruit collected from this level and your total score. The rest of the screen is where Gunnar is trapped.

For shooting, the thing to watch for are secret areas. They are green walls with stripes.

For moving up, jump for it. Gunnar can jump on to a platform from below, if it is thin enough, and not too high. You can also jump over a trampoline.

Beware of the enemies walking or flying around the levels. They will reduce your health. To keep from having to start again at the beginning if you die, touch a flag, that sometimes appear in the levels. If you are injured by an enemy, you will flash for a while, then become vulnerable again.

Inside the level you will occasionally see other special power ups. There are ones for a free life, mini-health, and full health. You may also see clocks and large silver rings. These are special collectables, so watch for them - Gunnar is very time consious, and likes to get as many clocks and rings as possible.

How to mod

There are three ways that the game can be modded: change the sprite sheet, add new or modify existing levels, or alter the source code.

How to change the sprite sheet:

  • Start your favorite paint program (such as GIMP or PhotoShop), and enable grid mode with a grid spacing of 16x16.
  • Once that is done, using the PDF from the doc directory to figure out what is in the squares.
  • The unique thing about the land squares is that they are tiled on screen like wallpaper.

How to modify the level:

  • The levels are all in individual text files called: map/level001.txt, ...
  • These can be edited in the level editor, or in a text editor (such as notepad).
  • The meaning of all of the symbols in the file are documented in the doc/fileformat_v2.txt.

Included is a Windows-based level editor (umed.exe) which can be compiled for Unix/Linux or MacOS from the source.

How to use the level editor:

  • Start it up, select either File->New or File -> Open, then choose a tile and paint away.
  • It uses the skin file gfx.png to in the preview window but the buttons show a predefined older skin - use the hover hints to help understand.
  • Some things (fruit, ground) can be painted, but everything else needs to be clicked. To reposition something, click nearby.

Add sounds with the file names:

  • "fruit.wav"
  • "jump.wav"
  • "rocket.wav"
  • "shoot.wav"
  • "spin.wav"
  • "start.wav"
  • "powerup.wav"
  • "checkpoint.wav"
  • "end.wav"
  • "die.wav"
  • "bomb.wav"
  • "empty.wav"

and these are used at various points if available.

Music is from "rush.it", if available. Or maybe from playlist.txt if available (only the first 5 songs are played).

In the src directory is the source code. Included are Bloodshed Dev-C++ project files for the Windows test game and level editor. Also included is the Makefile for the PSP version of the game.
