VaelthynGlen is a portrait-mode physics-based launching mobile game. Its core mechanic involves pulling a drifting launcher to charge power, then sending crystal projectiles toward prism targets resting on suspended shelves. Successfully knocking a prism off the shelf scores points, while three consecutive missed attempts end the round. As scores rise, both the target mass and shelf friction change dynamically, requiring flexible adjustments to launch strength, angle, and collision path. Easy to pick up yet offering strategic depth and tactile feedback, it is well suited for repeated attempts at higher waves and records.
