Premise & Single-Touch Spatial Combat
Caelum Exercitus is a vertical-scrolling HTML5 space-combat sandbox built in TypeScript and PixiJS, engineered from the ground up for fluid 60 FPS frame pacing on phones, tablets, and desktop browsers alike. Prototyped rapidly in weekend architectural sprints chronicled on the Crenet Games engineering blog, it rejects clumsy virtual thumbsticks in favor of intuitive single-touch tactical ship piloting against coordinated aerial enemy waves and heavy starship bosses.
Micro-Dodging, Weapon Upgrades & Dynamic Boss Patterns
Because one continuous touch or pointer drag governs horizontal and vertical craft positioning directly, high-level play revolves around economical micro-dodging rather than frantic wide sweeps. Grazing past interlocking projectile streams keeps your starfighter aligned beneath fragile interceptor wings while preserving wide escape lanes when fast dive formations enter the playfield. Defeated squadron leaders release modular upgrades that intensify forward firepower and defensive resilience cleanly without cluttering projectile contrast against the starfield. Stage-ending boss hulls introduce multi-sweep barrage rhythms that reward patience, lateral baiting, and disciplined edge spacing.
Lightweight WebGL Performance & Instant Browser Play
By keeping rendering pipelines focused inside hardware-accelerated TypeScript and PixiJS sprite batches, Caelum Exercitus boots rapidly over standard mobile data connections at caelum.crenet.games without bulky assets or native store wrappers. Whether sneaking in quick vertical survival runs on a phone touchscreen during a short break or dialing crisp pointer routing with mouse or keyboard controls on a desktop monitor, players read visual telegraph cues immediately thanks to sharp silhouette contrast, clean starfield layering, and responsive collision feedback. Maintaining calm spatial rhythm keeps upgrade chains alive even when boss patterns fill adjacent lanes.
| Control / Mechanic | Action Behavior | Piloting Tip |
|---|---|---|
| Single-Touch / Pointer Drag | Direct 1:1 Fighter Positioning | Keep small, smooth micro-adjustments inside dense fire |
| Automated Primary Fire | Continuous Forward Barrage | Focus completely on lane weaving while maintaining target alignment |
| Combat Upgrades | Enhanced Firepower & Hull Utility | Route through safe lanes before diving for drifting pickups |
| Stage Bosses | Multi-Phase Pattern Encounters | Read wide telegraph sweeps early and hug outer margins |
