The last two days have been a lot of good, solid work – the kind of work where you make slow-but-steady progress. Rainboids has seen a lot of incremental improvements, including:

• Gameplay improvements
• Streamlining UI and fine-tuning the HUD
• Graphical enhancements
• Tremendous graphical performance gains using WebGL
• Completely new sound effects
• Complete overhauls of existing weapons

… just to name a few things.

Gameplay

The game plays much faster with better access to its weapons, offering a lot of variety in gameplay. Gameplay is more powerup-centric, with the shop and upgrades taking a bit of a backseat as all weapons and skills are now unlocked right out of the gate.

The goal with these design decisions was to empower the player to tailor the gameplay experience to their enjoyment and feel free to try new things and experiment. Enhancing replay-ability was a core tenet informing many design choices. That, and streamlining UI and HUD so that the game provides a steady-stream of action with minimal interruptions.

Graphics

Besides that, careful attention was paid to all the little details, especially visual details. The starfield got a lot of love, and there were some critical WebGL enhancements. The game now features a hybrid Canvas + WebGL architecture, utilizing WebGL for particles and the background starfield for big performance gains. This allows for more on-screen particles and bigger explosions and more effects. It helps tremendously with later waves when there’s a ton of action and many on-screen objects.

The biggest teller is the particle pool size where recycled particle objects are kept – we were able to bump the size from 600 to 2500, effectively quadrupling the max number of on-screen particles. All this without any apparent hit in performance. That’s all thanks to WebGL.

Game Balance

Balance is the name of the game, and there will be many more iterations needed to truly balance the difficulty to keep things frenetic but also fun. Right now, the game leans in the direction of easy, and is arguably too easy – but the beginning is also intended to be that way in a bid to draw players in and get them invested. The future will definitely see much rebalancing in favor of more moderate difficulty.
