* Lisparuga
An Ikaruga demake created for the [[https://itch.io/jam/spring-2016-lisp-game-jam][Spring 2016 Lisp Game Jam]].
** Gameplay
Lisparuga is a minimalistic Ikaruga clone. The player can switch
between a light ship and a dark ship with the push of a button.
Bullets are either light or dark. When the player is light, dark
bullets kill and light bullets are absorbed. Vice versa when the
player is dark. Dark bullets deal 2x damage to light enemies and
vice versa.
For simplicity, the player will fight waves of enemies with a boss
fight at the end. The next wave enters when the current wave has
been defeated.
** Requirements
- [[https://gnu.org/s/guile][GNU Guile]] 2.1.2 or greater
- [[https://dthompson.us/pages/software/sly.html][Sly]] 0.2.0 or greater
** Building and running
Lisparuga uses the GNU build system, so building is
straightforward:
#+BEGIN_SRC sh
./configure
make
./pre-inst-env guile game.scm
#+END_SRC
** Graphic design
All graphics use the Dawnbringer 16 color palette.
*** Player sprite
The player sprite is 16x16 and has 3 frames: moving forward,
moving left, moving right.
*** Enemy sprites
Each enemy sprite has only 3 frames. The first two are the normal
sprite frames. Two frames are used so that the enemy can
"breathe" and appear as if it's moving and isn't just static. The
third frame is flashed when the enemy has been hit by a bullet.
*** Explosion sprites
Need both small and large explosion animations. Perhaps some
explosion animation on OpenGameArt can be recolored.
