Sipho 0.9.5 - Bounce Back

Bounce Mutation

Ever since the Mutation Creation Contest I've had this urge to implement a Bouncy Mutation. Many shoot-em-up games have this because bounciness is chaos and chaos is fun. You can land trick shots over corners, get surprised by enemy fire that bounces off or even create some Rube Goldberg machines. These are the ultimate goal of Sipho - a collection of mechanics that complement each other and allow creating complex systems for you to have fun with and beat the game.

A new Bounce Stat was added and a Mutation to go along with it

Thus the Bounce Stat has been added - as of now, only used by Projectile weapons - Flak, Sniper, Soul Eater and Sprayer. In the future other Zooids might support Bounce stat too, however, it can be trickier to balance as bounce can sometimes be non-beneficial.

One of benefits of having some Bounce is to guarantee your shots in tight areas. Now what do I use to reach that food?

For Projectiles Bounce works by keeping an internal counter of "remaining bounces". When a projectile hits a solid, non damageable object it checks if it has bounces left and bounces off if it does. If it doesn't - it dies as usual. This works with Obstacles and even with Spikes and Flails - projectiles can bounce off them!

Aquarium Obstacle Menu Overhaul

One of the silent and huge updates we had some time ago was updating Aquarium content. This was motivated by the need to tidy-up obstacle names for future game translations and update the old content in general. As a result we now have a pretty nifty spawnable object categorization with previews:

Notice the pleasing column/row ratio 😩👌

It is now also possible to change at which depth objects are spawned - on, below or above playable surfaces. In future, Decorations and Obstacles should become one category - as spawning Obstacles at non-collidable layers makes them Decorations and some Decorations can be interesting to collide with or even have some gameplay function.

Tooling, like changing depth or moving already spawned obstacles is also something I keep in mind.

Shady Business

One of graphical improvements that I really wanted to do for a long time were shadows.

Fancy name for a simple thing - blurry black outlines that get thicker if an object covers another object from higher distance.

Sipho action happens in deep waters and I really want to emphasize the atmosphere of this depth. While 2D by definition does not have depth we can do some tricks. One of which is parallax to add depth to lower layers - the deeper things are, the less they "move" when camera moves. This trick only works for deeper than playable layer. Playable layer can't have parallax as it would creation confusion around collisions. Higher layer in theory could have parallax, but it felt too distracting. So to add some depth emphasis on all layers at once I added Ambient Occlusion effect. It can be tweaked in Graphics Options for your liking!
