📜️ "blabla" 📜️

Basically it's a shoot-em-up with an evil twist.

Excellent Bifurcation came second in the www.shooter-dev.com 2007 Autofire competition! It doesn't have a website yet so all I have is a link to the competition registration thread on www.shooter-dev.com (with the game attached to the end of the first post). I'll make a proper website soon.

The aliens have attacked, and their ability to exist in either or both of their world and ours has given them an almost unsurpassable advantage. Take command of a special fighter craft capable of existing in both realities at once and drive them back!

The form your fighter takes on the left has double fast-firing cannons and can charge to release up to eight seekers. It is ideal for destroying small and weak but numerous enemies. The right-hand form has a single powerful cannon which fires slowly but does far more damage, and is more suited to taking out larger enemies. It can charge up to release a wave which passes through things, damaging them as it goes (unlike the beam weapons, which only hit anything once no matter how thick it is). You can switch them between the worlds depending on what kind of firepower you need where.

The only vulnerable parts of your ship are the white parts at the centre. This means that the small form is much better at dodging than the large one. The only dangerous parts of bullets are the brightest (yellow or white) parts. Also, if you are shot down the form which was hit emits a green shockwave instead of a yellow one. You get an extra life each 1500 points.

There are three difficulty levels: Easy (good for beginners, but not really all that easy); Medium (for people who have got used to the bifurcation); and Hard (for that guy I saw on Youtube playing Ikaruga with both players at once). The game will probably seem impossible at first, but after a bit of practice the two halves of your brain will start to separate and the pathways between bullets will become clear. You can also choose to start on either Stage 1 or Stage 2.

You can change settings like windowed vs fullscreen, volume and whether vsync is used by editing init.txt in any text editor (I didn't want to spend competition time writing a proper menu interface for setting options). Instructions are in the file. Personally I recommend playing in fullscreen, but the default is windowed. If you are having problems with skipping frames, close down other applications and try fullscreen - it seems to help. Turning vsync off should also help performance, but if your computer was built in the last 5 years it shouldn't have any trouble running this game.

🚧️ Installation ➜ 🚀️ Launching [fr]

⌨️🖱️🎮️ CONTRÔLES:
Default controls (but they're redefinable):
Move around with the arrow keys;
Z fires;
X charges your charged weapons;
C switches your two forms between the different worlds;
A turns autofire on/off (autofire is just like holding down Z).

🕵️ Test [fr]

🕵️ Test (1.0) de goupildb :
Une belle réalisation avec un graphisme soigné, de bons effets sonores, une belle bande son et une bonne interface.
J'ai trouvé le gameplay très difficile et un peu agaçant car l'on doit jouer simultanément avec les 2 vaisseaux sur un écran splitté verticalement.
