Starforge is an engaging endless block-stacking arcade game designed for Android devices. Players control a sliding plank that drops blocks onto a growing tower, with the objective of stacking as many blocks as possible. Careful alignment is crucial, as misaligned blocks will fall away, causing the tower to narrow. The game does not have a definitive end; instead, it increases in difficulty as players progress, introducing faster fall speeds and varying block widths. The score reflects the number of successfully stacked blocks, encouraging players to improve their personal bests.

The user interface features a full-screen background image on the main menu, with straightforward navigation options for starting the game, accessing help, or exiting. During gameplay, a simple solid-color background keeps the focus on stacking. An accessible pause feature allows players to restart, resume, or exit the game at any point. Upon completion, players are presented with their current score and historical high score, motivating them to keep playing and improve.
