The game's core is well-coded, lean, and performs fast. However, significant polish is required. Major issues include:
The absence of a game-over screen.
A critical bug allowing players to rotate and move landed blocks, enabling them to phase through others and trivializing the challenge.
Inaccessible audio settings; music cannot be adjusted or turned off, and there are no other sound effects.
The inappropriate requirement for players to modify source code to adjust game settings.
While the foundation is solid, these oversights in basic user experience and gameplay integrity currently hold it back from being good.
