Game Summary
- Single player puzzle game
- Player uses a jump interface to jump at various
heights and angles - Must jump over obstacles and onto moving objects
to reach level exit
3
Story Abstract
- Main character is kidnapped and used for science
experiments - Given super jumping strength
- Is used to test the effectiveness of the
procedure - Told that if he can pass several obstacle
courses, he will be free to go - But is it true?
4
Appearance
- Static screen for each level
- Simple sprites and backgrounds
- Simple coloring
- Interface consists of power meter, death counter,
and mouse cursor - Meter fills up as player charges jump strength
- Four midi songs in the game
- Title, story, game play, ending
5
Interface
- Power meter in upper left
- Death count in upper right
- Red mouse cursor to set jump path
6
Interface
7
Player Actions
- Hold mouse button to charge a jump
- Release button and character will jump in the
direction from the character to the mouse pointer - Takes about two seconds to fully charge
- Can charge jumps in the air
- Jumps follow a parabolic path
- Player will have no air control
- Use jumps to avoid obstacles and reach (moving)
platforms
8
Strategies and Motivations
- Number of total deaths used for scoring
- Player goal to reach the door
- Lack of air control
- Causes player to plan ahead
- Puzzle solving skills
- Quick reaction moments
- Falling/Moving platforms the player needs to jump
off of quickly - Needs to time when to start the jumping to
complete puzzles
9
Level Summary
- Three different levels
- Players automatically transition to next level
after completing one by stepping onto the door - Levels get progressively harder
10
Story Progression
- No story advancement aside from beginning and end
- Situation doesn't change from level to level
- Ending is open, lets the player decide how it ends
11
Hardware Specification
- Had trouble running on the machines during the
game fair (unsure of the exact problem) - Has no trouble on an old Dell with 2Ghz single
core processor, 512 MB of RAM and basic
integrated graphics - Needs minimal graphics acceleration
12
Software Specification
- Designed using DirectX
- Machine needs DirectX installed to run the game
13
Algorithm Style
- Physics
- Physics will work by using x and y velocity to
move the sprites each frame. - Gravity will be applied to the y velocity each
frame, making it more negative each time - Collision
- Collision check based on bounding boxes around
the sprites/environment - Floor done using color scan
- Checks made only when an object's x position (y
position on vertical spikes) puts it in place to
collide with the character.
